Question

which of the following is/are appropriate displays for the distribution of heights of students in a college statistics class of 53 students?

i. histogram
ii. mosaic plot
iii. stem-and-leaf plot

○ i and iii only
○ ii only
○ i, ii and iii
○ iii only
○ i and ii only

Explanation:

• Histogram: Good for showing distribution of continuous data (heights) by grouping into intervals.
• Mosaic Plot: Used for categorical data relationships, not single continuous variable distribution.
• Stem - and - leaf Plot: Displays distribution of continuous data while preserving raw data, suitable for heights.

So I (Histogram) and III (Stem - and - leaf Plot) are appropriate.

Answer:

I and III only
