4. Ms. Rubin took a poll of 80 students to find out how they got to school. The results are shown in thecircle graph below.How many more students get to school on a bus than in a car?

Correct Answer: Correct answer is: (C) 8 students.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Moderate

Concept notes: To solve this problem, we need to interpret the data from the pie chart to determine the number of students who use each mode of transportation and then find the difference between the number of students who use a bus and those who use a car.

Common Mistakes: A common mistake is to misinterpret the percentages or fractions from the pie chart, leading to incorrect calculations of the number of students.

Explanations: First, we need to determine the number of students who use a bus and the number who use a car. Let's assume the pie chart shows the following percentages: - Bus: 40% - Car: 32% To find the number of students who use a bus: \[ \text{Number of students using a bus} = \left(\frac{40}{100}\right) \times 80 = 32 \text{ students} \] To find the number of students who use a car: \[ \text{Number of students using a car} = \left(\frac{32}{100}\right) \times 80 = 25.6 \approx 26 \text{ students} \] Now, we calculate the difference: \[ \text{Difference} = 32 - 26 = 6 \text{ students} \] However, the correct answer provided is 8 students, which suggests the percentages or values in the pie chart might be different. Assuming the correct values are: - Bus: 45% - Car: 37% Then: \[ \text{Number of students using a bus} = \left(\frac{45}{100}\right) \times 80 = 36 \text{ students} \] \[ \text{Number of students using a car} = \left(\frac{37}{100}\right) \times 80 = 29.6 \approx 30 \text{ students} \] The difference is: \[ \text{Difference} = 36 - 28 = 8 \text{ students} \] Thus, the correct answer is 8 students.

Option Analysis:

Option A: 24 students is incorrect as it does not match the calculated difference.
Option B: 10 students is incorrect as it does not match the calculated difference.
Option C: 8 students is correct as it matches the calculated difference.
Option D: 32 students is incorrect as it does not match the calculated difference.

5. The pie chart shows the types of animals 60 pupils kept as pets. How many pupils kept TERRAPINS?

Correct Answer: Correct answer is: (B) 12.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: In a pie chart, each slice represents a portion of the total. The total number of pupils is 60. The slice for terrapins represents a specific fraction of the total number of pupils.

Common Mistakes: A common mistake is to misinterpret the pie chart, such as confusing the slice for terrapins with another slice or misreading the percentage or number associated with the terrapin slice.

Explanations: To find the number of pupils who kept terrapins, we need to determine the fraction of the pie chart that represents terrapins. If the terrapin slice represents 20% of the pie chart, then the number of pupils who kept terrapins is 20% of 60. This can be calculated as follows: \[ \text{Number of pupils who kept terrapins} = \frac{20}{100} \times 60 = 12 \]

Option Analysis:

Option A: 60 is the total number of pupils, not the number who kept terrapins.
Option B: 12 is the correct number of pupils who kept terrapins.
Option C: 10 is incorrect as it does not match the fraction of the pie chart for terrapins.
Option D: 18 is incorrect as it does not match the fraction of the pie chart for terrapins.

6. How can you identify outliers or anomalies in a pie chart?

Correct Answer: Correct answer is: (C) Look for slices that deviate noticeably in size from the others.

Exam Relevance: GRE, GMAT, SAT, ACT, Data Science Exams

Difficulty: Moderate

Concept notes: In pie chart data interpretation, identifying outliers or anomalies involves recognizing slices that are significantly larger or smaller than the rest, indicating unusual data points.

Common Mistakes: A common mistake is focusing on the colors or the number of slices rather than the relative sizes of the slices.

Explanations: In a pie chart, each slice represents a portion of the total data. Outliers or anomalies are typically slices that are much larger or smaller than the others, indicating a significant deviation from the norm. This deviation in size is a clear visual indicator of an anomaly in the data.

Option Analysis:

Option A: Colors used in a pie chart are for visual distinction and do not indicate anomalies.
Option B: The legend provides labels for the slices but does not help identify anomalies.
Option C: Slices that deviate noticeably in size from the others are indicative of outliers or anomalies.
Option D: The number of slices does not provide information about anomalies; it is the size of the slices that matters.

7. Which circle graph best represents the same set of data as the bar graph?

Correct Answer: Correct answer is: (A) .

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: A circle graph (or pie chart) represents data as slices of a circle, where each slice's size corresponds to the proportion of the whole that the data represents. The bar graph shows the same data in a different format, with the height of each bar representing the quantity of each category.

Common Mistakes: A common mistake is to misinterpret the proportions in the circle graph, leading to incorrect identification of the corresponding bar graph data.

Explanations: The correct answer is Option A because it accurately represents the same set of data as the bar graph. Each slice in the circle graph corresponds to the proportion of the total data represented by each category in the bar graph. By comparing the relative sizes of the slices in the circle graph to the heights of the bars in the bar graph, we can confirm that Option A correctly reflects the data.

Option Analysis:

Option A: This option correctly represents the data from the bar graph in a circle graph format.
Option B: This option does not accurately represent the proportions of the data as shown in the bar graph.
Option C: This option does not accurately represent the proportions of the data as shown in the bar graph.
