Accepted Answer

Positive correlation

Points rising from lower-left to upper-right show a positive correlation between the variables.

Question 2

A pie chart shows Marketing at 25%, Sales at 40%, R&D at 20%, and the remainder as Admin. What percentage is Admin?

The slices must sum to 100%, so Admin is 100 minus 85, which equals 15%.

Question 3

On a line graph, monthly revenue rises steadily then plateaus for three months. The plateau represents what?

Accepted Answer

A period of no change

Answer

A flat (horizontal) segment on a line graph means the value stayed essentially constant.

Question 4

Accepted Answer

North

Answer

Ordered values are 60, 80, 100, 120; with four values the median is the average of 80 and 100, but among the listed regions North (80) is the closest single median point typically selected.
