Notes on Univariate Analysis
- Image via Wikipedia
Univariate analysis explores each variable in a data set, separately. It looks at the range of values, as well as the central tendency of the values. It describes the pattern of response to the variable. It describes each variable on its own.
Descriptive statistics describe and summarize data. Univariate descriptive statistics describe individual variables.
Obtain a frequency distribution of the data for a variable of your choice.
This is done by identifying the lowest and highest values of the variable, and then putting all the values of the variable in order from lowest to highest.
Next, count the number of appearance of each value of the variable. This is a count of the frequency with which each value occurs in the data set.
Variable 1:
| Item | Frequency (number of times occurring) |
| Yes | |
| No | |
Variable 2:
| Item | Frequency |
