Question
From what kinds of variables would a histogram be generated?
Solution
A histogram can be generated from quantitative or numerical variables. These variables can be either continuous or discrete.
-
Continuous Variables: These are variables that can take any value within a certain range. For example, height, weight, temperature, etc. When these variables are used, the histogram will have bars of varying heights representing the frequency of observations within certain ranges of values.
-
Discrete Variables: These are variables that can only take certain values. For example, the number of children in a family, the number of cars a person owns, etc. When these variables are used, the histogram will have bars representing the frequency of each specific value.
In both cases, the variables used should be able to be sorted in an ascending or descending order. This is because a histogram represents the distribution of data by forming bins along the range of the data and then drawing bars to show the number of observations that fall in each bin.
