Today we will begin to look at the characteristics of individual variables. We call this univariate analysis because we are looking at one variable at a time. In two weeks we will begin to look at two variables. By the end of the term we will by looking at more than two variables at the same time.
Univariate analysis looks at the characteristics of single variables.
Today we will look at the variable AGE because it is a ratio level variable. A table will appear that shows you how many people are of each age. For example 2 respondents were 18 years of age. You can print this page out if you like to be able to look at all the answers at once. Next we will calculate the average age for this population and the standard deviation.
