Question

1. bad dotplot janie asked 10 friends how many photos they posted on instagram yesterday. then she made the following dotplot to display the data. whats wrong with janies dotplot?

Explanation:

A dot - plot should have a consistent scale on the number line. In Janie's dot - plot, the intervals between the numbers on the number line are not equal. For example, the interval between 3 and 5 is 2, between 5 and 6 is 1, between 6 and 9 is 3, and between 9 and 12 is 3. A proper dot - plot requires a uniform scale (equal intervals) on the number line to accurately represent the data distribution.

Answer:

The intervals on the number line are not equal.
