Problem 22

An experiment was done to compare two methods of measuring the calcium content of animal feeds. The standard method uses calcium oxalate precipitation followed by titration and is quite time-consuming. A new method using flame photometry is faster. Measurements of the percent calcium content made by each method of 118 routine feed samples (Heckman 1960) are contained in the file calcium. Analyze the data to see if there is any systematic difference between the two methods. Use both parametric and nonparametric tests and graphical methods.

STAT 110: Notes for Week of 9/13/16  Chapter 10 o In order to describe data, you must figure out if it is quantitative or categorical. o Quantitative Variable: a variable that measures something already in numerical form, ex. inches of a piece of paper, weight of a person, IQ, etc. o Categorical Variable: measures something that needs to be put into categories and/or given numerical value, ex. favorite color, ethnicity, current feelings, etc. o Distribution of a variable: tells what values of a variable occur and how often they occur, ex. 20 people like the color blue, 0 people like the color orange, etc.  Distributions can be described through tables, graphs, or num
