Question

what was the longest measurement? length of insects (in inches) 0 1 2 3 4 inches

Explanation:

Step1: Identify axis values

The horizontal axis marks 0, 1, 2, 3, 4 inches, with each major tick split into 2 smaller intervals, so each small tick is $\frac{1}{2}$ inch.

Step2: Locate rightmost data point

The rightmost "X" is at the tick 2 intervals right of 3. Calculate the value: $3 + 2\times\frac{1}{2} = 3 + 1 = 3.5$ or $\frac{7}{2}$.

Answer:

$\frac{7}{2}$ (or 3.5) inches
