Question

1. question 7: which of the following is a method to determine if a data set is linear? a) evaluating the data points at different intervals b) calculating the median of the data points c) observing if the data points fall on a straight line d) determining if the data points have a similar range

Explanation:

Step1: Analyze option a

Evaluating data points at different intervals does not directly determine linearity.

Step2: Analyze option b

Calculating the median of data points is about central tendency, not linearity.

Step3: Analyze option c

A linear data set has a constant rate of change, which means the data points lie on a straight line.

Step4: Analyze option d

Determining if data points have a similar range is about spread, not linearity.

Answer:

C. Observing if the data points fall on a straight line
