30. In a histogram, the bars represent: — Classes or bins of data
31. When constructing a histogram, the data must first be grouped into: — Class intervals or bins
32. What is the primary advantage of a pie chart? — It effectively visualizes the relative sizes of parts to a whole.
33. What is the primary advantage of using a frequency polygon over a histogram for comparing distributions? — It is easier to overlay multiple frequency polygons on the same axes.
