Question 1

A scatter plot shows points scattered from lower-left to upper-right. What kind of relationship does this suggest?

Accepted Answer

Positive correlation

Answer

Points trending from lower-left to upper-right indicate that as one variable increases, the other also tends to increase, showing a positive correlation.

Question 2

Which measure of center would be MOST affected by an extremely large outlier in a data set?

Accepted Answer

Mean

Answer

The mean uses every value in its calculation, so one very large value pulls the mean upward significantly.

Question 3

A student reads a bar graph and says, 'January had exactly twice as many rainy days as February.' The bars show January = 10 and February = 5. Is the student correct?

Accepted Answer

Yes, because 10 is exactly twice 5

Answer

10 ÷ 5 = 2, confirming that January's value is exactly twice February's value.

Question 4

What does the range of a data set tell you?

Accepted Answer

The spread between the smallest and largest values

Answer

The range is calculated by subtracting the minimum value from the maximum value, showing how spread out the data is.

Question 5

A frequency table shows how many students scored in each grade range on a test. What does 'frequency' mean in this context?

Accepted Answer

How often each score range occurred

Answer

In a frequency table, frequency refers to the count of how many times each value or range of values appears in the data.
