Question 1

In a two-way frequency table, what does the value in the bottom-right corner (the grand total cell) represent?

Accepted Answer

The grand total represents the sum of ALL individuals or observations in the entire dataset, combining every row and column category.

Question 2

On a double bar graph comparing two groups across several categories, how do you determine which group scored higher in a specific category?

Accepted Answer

Compare the heights of the two bars side by side for that category; the taller bar represents the higher value for that group.

Question 3

When a table displays data in scientific notation (e.g., 3.2 × 10⁴), what is the first step to comparing two values accurately?

Accepted Answer

Convert both values to the same power of ten (or to standard notation) before comparing, ensuring the exponents match so the coefficients can be directly compared.

Question 4

A pie chart shows a sector labeled 72°. What percentage of the whole does this sector represent?

Accepted Answer

20%, because 72 ÷ 360 = 0.20, and multiplying by 100 gives 20%.

Question 5

What is a key difference between a histogram and a bar graph?

Accepted Answer

A histogram displays the distribution of continuous numerical data with no gaps between bars, while a bar graph compares distinct categorical data with spaces between bars.
