1. Which of the following is a basis of classification of a table?

Correct Answer: Correct answer is: (D) All of these.

Exam Relevance: GRE, GMAT, CAT, Data Science Exams

Difficulty: Moderate

Concept notes: The classification of a table in data interpretation can be based on various criteria such as purpose, construction, and originality.

Common Mistakes: A common misunderstanding is that only one of the criteria (purpose, construction, or originality) is used for classification, when in fact, all three can be relevant.

Explanations: In table data interpretation, a table can be classified based on its purpose, which refers to the intended use or function of the table. It can also be classified based on its construction, which involves the structure and design of the table. Additionally, the originality of the table, which refers to whether the data is primary or secondary, can also be a basis for classification. Therefore, all of these criteria can be used to classify a table.

Option Analysis:

Option A: Purpose is a valid basis for classification.
Option B: Construction is a valid basis for classification.
Option C: Originality is a valid basis for classification.
Option D: All of these are valid bases for classification.

2. The table shows the number of line segments needed to draw different numbers of hexagons. How many line segments are needed to draw 3 hexagons?

Correct Answer: Correct answer is: (D) 18.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Moderate

Concept notes: To determine the number of line segments needed to draw 3 hexagons, we need to understand the pattern in the table. Each hexagon has 6 sides, and the number of line segments increases as more hexagons are added.

Common Mistakes: A common mistake is to assume that the number of line segments is simply 6 times the number of hexagons, without considering the shared sides between adjacent hexagons.

Explanations: To find the number of line segments for 3 hexagons, we need to consider the shared sides. Each hexagon has 6 sides, but when hexagons are adjacent, they share sides. For 3 hexagons, the pattern in the table shows that the number of line segments is 18. This can be verified by counting the sides and shared sides in a typical arrangement of 3 hexagons.

Option Analysis:

Option A: 27 is incorrect because it assumes each hexagon has 6 sides without considering shared sides.
Option B: 20 is incorrect because it does not match the pattern in the table for 3 hexagons.
Option C: 7 is incorrect because it is far too low and does not match the pattern in the table.
Option D: 18 is correct as it matches the pattern in the table for 3 hexagons.

Mnemonic: Hexagon, Six Sides, Shared Sides

3. The table shows how the heights of two trees are changing over time. Which best describes the relationship shown in the table?

Correct Answer: Correct answer is: (B) Tree Y is growing 1 foot more each year than tree X.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: The question requires interpreting the relationship between the growth rates of two trees over time from a table.

Common Mistakes: A common mistake is to confuse the absolute height difference with the growth rate difference.

Explanations: To determine the relationship between the growth rates of the two trees, we need to compare the height differences year by year. If tree Y grows 1 foot more each year than tree X, then the difference in their growth rates is consistent. This means that the height difference between tree Y and tree X increases by 1 foot each year. The correct answer is that tree Y is growing 1 foot more each year than tree X.

Option Analysis:

Option A: This option suggests that tree X is growing 2 feet more each year than tree Y, which is incorrect based on the table data.
Option B: This option correctly states that tree Y is growing 1 foot more each year than tree X, which aligns with the data in the table.
Option C: This option suggests that the height of tree X is 3 feet greater than the height of tree Y every year, which is not supported by the table data.
Option D: This option suggests that the height of tree Y is 2 feet greater than the height of tree X every year, which is not supported by the table data.

4. Craig is making three recipes for his party. He has a container of flour on his kitchen scale. The table shows the total change in weight of the flour on the scale after each of the three recipes. What is the average change in the amount of flour, in ounces, used in the three recipes?

Correct Answer: Correct answer is: (A) $-3\frac{1}{3}$.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Moderate

Concept notes: To find the average change in the amount of flour used in the three recipes, we need to sum the changes in weight and then divide by the number of recipes.

Common Mistakes: A common mistake is to misinterpret the sign of the change in weight, leading to incorrect calculations.

Explanations: Let's assume the changes in weight of the flour for the three recipes are as follows (in ounces): - Recipe 1: -4 ounces - Recipe 2: -2 ounces - Recipe 3: -4 ounces To find the average change, we sum these values: -4 + (-2) + (-4) = -10 ounces Next, we divide the total change by the number of recipes: -10 / 3 = $-3\frac{1}{3}$ ounces Thus, the average change in the amount of flour used in the three recipes is $-3\frac{1}{3}$ ounces.

Option Analysis:

Option A: Correct. The average change in the amount of flour used is $-3\frac{1}{3}$ ounces.
Option B: Incorrect. The value 2 does not match the calculated average change.
Option C: Incorrect. The value -10 is the total change, not the average change.
Option D: Incorrect. The value -3.3 is a decimal approximation, but the exact answer is $-3\frac{1}{3}$.

5. Which graph correctly shows the information in the data table?

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

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Moderate

Concept notes: The correct graph should accurately represent the data provided in the table, including the correct values and trends.

Common Mistakes: A common mistake is to misinterpret the scale or the values in the graph, leading to incorrect representation of the data.

Explanations: Graph C correctly represents the data from the table. Each point on the graph corresponds to the values in the table, and the trend is accurately depicted. The other graphs either have incorrect values or do not accurately represent the trend shown in the table.
