Lesson Steps

Step Type Explanation Answer

1

Problem

The table shows the results of a survey. Display the data in a circle graph.

1

2

Step

The circle graph B matches the data in the table exactly. Here is a breakdown of the data it shows:

→ Fall: 48%
→ Winter: 16%
→ Spring: 29%
→ Summer: 20%

3

Step

Therefore, Fall has the highest percentage (48%), it would take up the largest portion of the circle graph. The circle graph B matches this description exactly.

4

Choice.A

This circle graph incorrectly depicts the data
Fall Slice: While Fall is larger than Winter and Summer, it’s not significantly larger to represent 48%

Spring Slice: Spring appears larger than Winter, which contradicts the data (Winter has 16% and Spring has 29%)

1.1

5

Choice.B

This circle graph (the one you mentioned as correct) accurately represents the data
Fall Slice: The largest slice represents Fall (around 48%), which aligns with having the highest percentage

Other Slices: Winter, Spring, and Summer slices are all smaller than Fall, and their relative sizes somewhat correspond to their data percentages (Winter smallest, then Spring, then Summer)

6

Choice.C

This circle graph also misrepresents the data
Fall Slice: Fall is smaller than Spring and Summer, contradicting its 48% share

Spring and Summer Slices: Spring and Summer slices are larger than Fall, although Summer has a lower percentage (20%) than Spring (29%)

1.3

7

Choice.D

Similar to option C, this graph also inaccurately portrays the data
Fall Slice: Fall is again smaller than Spring and Summer, despite having the highest percentage (48%)

Spring Slice: The largest slice is Spring, which is incorrect according to the data
