Step 1 of 3

STAT 2004 Week 2 Lecture 5 Fri. 01/27/17 Observational study: data analysis where researcher does not interfere with data outcomes Experiment: researcher directly interferes with data outcomes y imposing treatments and controls Observational  An example of an observational study would be a survey: did you get a flu shot  Observational studies help establish correlation Experiment  Randomly assign a treatment group (flu shot) and a control group (no flu shot)  Help establish causation Sample frame: data has to be assigned with a number (a list of people, each have a number that doesn’t repeat) 194,147,134,33,62  Strata: (singular- stratum): subgroups or demographics of a population  Stratified random sample: first break population into strata; then randomly select from each stratum  Take the same sample size from each stratum Cluster random sample: first divide population into clusters (often but not always by location)  All members of a cluster are measured or treated  The cluster s randomly picked but the things in the cluster are not random because all of them are being measured or tested Example Research question: Are VT students happy with the game day experience Cluster sample: randomly select 20 rows in cassell, poll everyone in those rows (sample frame: list of rows 1-600) stratified sample: strata (undergrad, graduate, alumni, other) (sample frame: list of all people, broken down by stratum) select 20 from each stratum
