qualities and quantify them in a way that could place individuals in the correct job later there was a move towards MANIPULATION of environment to get more work out of them realized motivation isn t necessarily a characteristic able to get more through relationships mood JOB SATISFACTION 0 measured people performance and now satisfactionQUALITY o buttttt testing was not very good at placing

prediction and control of some phenomenon of interest Science has common methods Science is a logical approach to investigation 0 Based on a theory hypothesis or basic interest Science depends on data Gathered in a laboratory or the field GOALS OF PSYCH 1 describe 2 explain 3 predict 4 control Employing a set of standardized testing that is highly rational logical rooted in the scientific method Hypothesis 0 Variables 0 Controls 0 ExperimentationTESTING Materials Research must be communicable open amp public WANT to be accessible Research published in journals reports or books 1 Methods of data collection described 2 Data reported 3 Analyses displayed for examination 4 Conclusions presented Scientists set out to disprove theories or hypotheses Goal Eliminate all plausible explanations except one 0 Confirmation Bias Selectively focusing on info that confirms theories we already have 0 Preconceived notions that support our own perspectives and skew data goal of science is to DISPROVE a theory 0 Eliminate all plausible explanations say why X does NOT prove Y Scientists are objective 0 Expectation that researchers will be objective amp not influenced by biases or prejudices 0 Can t fall to biases confirmation biases 0 People should draw conclusions from the facts Role of Science in Society 0 Expert witness in a lawsuit 0 Permitted to voice opinions about organizational practices 0 Often an IO psychologist Why do IO psychologists engage in research 0 Better equip HR professionals in making decisions in organizations 0 Higher levels productivity profits motivation 0 Provide an aspect of predictability to HR decisions 0 Need to be able to know with certainty how to manipulate and influence people 3 Research Designs 1 Experimental 0 Random assignment of participants to conditions 0 Random population strata Conducted in a laboratory or the workplace 0 Manipulate variables independent and dependent Have a control group and experimental of random people 0 HIGH degree

Copyright Clearance Center Inc Week 3 91115 142 PM Review 3 types of research design Experimental 0 Random assignment of participants to conditions 0 Conducted in a laboratory or the workplace 0 There are Independent and Dependent variables that are MANIPULATED Independent variable Dependent variable The variable that is BEING MEASURED in an experiment depends on the independent variable a Researchers want to discover if listening to classical music helps students earn better grades on a math exam In this example the scores on the math exams are the dependent variable a Researchers want to know whether firstborn children learn to speak at a younger age than secondborn children In this example the dependent variable is the age at which the child learns to speak a Researchers are interested in seeing how long it takes people to respond to different sounds In this example the length of time it takes participants to respond to a sound is the dependent variable Quasiexperimental o Nonrandom assignment of participants to conditions Nonexperimental 0 Does not include manipulation or assignment to different conditions 0 Is a form of measurement observations 0 2 common designs Observational design Observes and records behavior SurveyQuestionnaire design most common 0 23 IO use nonexperimental designs Science must be rooted in TRUTH Accurate reliable consistent so we need to form a systematic process to obtain the Truth As IO psychologists people are seen as quantitative data want to be able to make decisions about peoplecompare them scoring helps this So WILL this

the data collected construct a histogram xaxis has the 17 scale of confidence yaxis is the of repeats Quantitative data methods Rely on tests rating scales questionnaires amp physiological measures yields results 0 gives a very pure measurement get the puzzle pieces 0 EX Qualitative data Include procedures like observation interview case study amp analysis of written documents Generally produce flow diagrams amp narrative descriptions of eventsprocesses 0 give us subjective insightsconstructs a broad overview of the puzzle 0 EX Interviews 0 Run risk of contaminationbiases mood bias 0 Hypothetical constructs as an explanatory variable not concrete used as a tool used to facilitate understanding of human behavior Quantitative and Qualitative are NOT mutually exclusive Triangulation technique capturing both quantitative and qualitative to hone in a full view of the study 0 Examining converging information from different sources qualitative and quantitative research 0 Combining all aspects to create a holistic view we get puzzle pieces quantitative but need to have an abstract idea qualitative in order to assemble the puzzle Generalizability in research 0 Application of results from one study or sample to other participants or situations 0 The more areas a study includes the greater its generalizability the broader context is derived from more diverse samplings larger number of subjects 0 Want to be able to make findings more generalized more predictable is applying results from one study to a larger scale 0 Every time a compromise is made the generalizability of results is reduced IF more variablesless controls are used it is much harder to pinpoint the results of an experiment versus additional influencers o Generalizability decrease over TIME continual process Time Job Titles Participants Personality consciences as a predictor for job performance 0 Want to sample the ENTIRE organization 0 Measure both confidence and job performance 0 Now any future applicants will receive a confidence test Their scores will determine ifI should hire them based on this exp 0 However if you had just tested engineers job title you cannot expect the same results generalizing isn t possible Control in research Experimental control o Eliminates influences that could make results less reliable or harder to interpret o Standardize the experiment as much as possible control the experience allowing us to measure a SINGLE point Statistical control 0 Statistical techniques used to control for the influence of certain variables Assess other variables that might be making an impact a Ex selfesteem measure selfesteem and performance but maybe mood affects esteem So theoreticaly positive mood may have the correlation SO if you add mood data point you are able to account for it in experiment Descriptive statistics Summarize organize describe sample of data Frequency Distribution 0 Horizontal axis Scores running low to high 0 Vertical axis Indicates frequency of occurrence Central tendency the degree of clustering of the values of a statistical distribution that is usually measured by the arithmetic mean mode or median Score Distributions 3 measurescharacteristics Measures of central tendency 0 Mean the average of the data 0 Mode most often data component repeated 0 Median Once data is arranged low to high middle Standard Deviation variabilityamount allowed to vary before deemed an outlier Variability 0 Standard deviation an averaging the amount it is allowed to vary ie STD 13 means with a mean of 5 can vary fromwithin 33 to 63 o The variance distribution STD 2 The average squared deviation from the mean 0 The range one measure of the amount of error we have Index means measure Histogram shapes Lopsidedness or skew Mean is affected by high or low scores median is not 0 Mean pulls in direction of skew Histograms random data assembled into a graph Positive skew scores are high ranged To the RIGHT of the MEDIAN Negative skew scores arranged at the lower to the LEFT of the Median All depends on where the MEDIAN is ll 10 9 Mean Median Mode 9 Mode 7 7 Median Mean 6 6 Frequency Frequency J 48 10 U 45 55 59 100 Test

Straight line that best fits the scatterplot and describes the relationship between the variables in the graph Correlation Coefficient tells in z score units 0 Statistic or measure of association Reflects magnitude numerical value amp direction or of relationship between 2 variables Ranges from 000 and 100 o COEFFICIENT IS THE SLOPE OF THE Z SCORE Correlation Coefficient has a valence and magnitude Ranges from 1 to 1 Positive correlation gt As one variable increases other variable also increases amp vice versa Positive slope Negative correlation gt As one variable increases other variable decreases amp vice versa negative slope Positive linear correlation 100 75 w 1 50 iraining Grade l I l I l I I 25 I I I I I l 0 25 50 511 75 100 Cognitive Test Score High Low Low High rxy 00 Low Low Inferential Statistics High High Low X High High Low Low High rxy 50 X LOW Low High X High Low High Aid in testing hypotheses amp making inferences from sample data to a larger samplepopulation Creating inferences from a study 0 Ex a mental test is given to two groups High school kids and College kids IF the results were that the lower MEAN scoring group was the high school group it could be inferred that education is associated with higher test scores 0 Why can you do this data is an average mean scores representing the group outliers mess up generalizations 0 Include ttest Ftest chisquare test From class 2 Review Correlation Coefficient is a statistical element that tells the amount of correlation between variables 1 to 1 range X gt 05 is statistically significant negative correlation ex the more you drink the less likely you will attend class positive correlation ex the more you come to class higher grade Even IF there is an apparent correlation does not establish a cause effect relationship amp Vice versa ex no correlation between stress and performance BECAUSE there is a curvilinear line line of best fit straight Too low of stress does not increase performance BUT too much stress is overwhelming GOAL of IO Psych 1 Describe Explain Control PREDICT 3 types IO personnel Predicting organizational MANIPULATION Human engineering Environment Past 0 Measuring abilities to match with a job Predict performance 0 Heavily personnel based Need to be able to repeat a test and RELY that it will yield similar results 0 RELIABILITY Need to be able to double check that our info is Validaccurate o VALIDITY TEST Reliability testing 0 The CONSISTENCY of a measure 0 can we predict the outcome of this experiment once repeated Is the conclusion we drew consistent TestRetest reliability 0 Testing to see if over time results are the same consistent answers 0 There is often contamination in experiments 0 Tested with the EXACT same test to same individual Pitfall amount of time between two tests less time consistency of Memory essentially butttt over too much time integrityfeelings may change D But is this due to personal change or testing inconsistencies Not always practical to testretest Reliability coefficient RANGE is 0 to 1 but IF there was a perfect 1 chances are there is an additional factor working ie memory Equivalent forms reliability 0 Type of reliability calculated by correlating measurements from a sample of individuals who completed 2 different forms of the same test 0 Can have 5 very similar questions in one test to get a bit of consistency slightly reworded but with the same end meaningmeasurement Pitfall If there are too many questions people lose interest can put a bit more emphasislevel of importance on the first answer in each set U Ex 1 and 2 more related than 1 and 3 But 2 and 3 are closer than 1 and 3 I Take average of all possible correlations Chrombox alpha tells internal reliability within a test a Ex SAT Test a Different tests that measure the same equal info Criterion the outcome the thing we desire Predictor the psychological testing informed to test for the criterion Predictive validity Criterionrelated validity design in which there is time lag between gathering test scores and performance data 0 Able to predict what WOULD have happened had you actually used the test scores to make the hiring decisions 0 Later figure the validity Concurrent validity Criterionrelated validity design in which there is NO time lag between gathering test scores and performance data 0 Test scores are concurring with performance data 0 Give test to CURRENT employees IF performances are good you can use the test later for new hires Still are predicting criterion Construct validity Investigators gather evidence to support decisions or inferences about psychological constructs Content Validity
