Question

1. three scatterplots are shown below.

place the order of the correlation value from least to greatest.
(a) ii, iii, i
(b) ii, i, iii
(c) iii, i, ii
(d) i, iii, ii
(e) iii, ii, i

Explanation:

Step1: Analyze scatterplot I

Scatterplot I has points that are very spread out with no clear linear pattern. So, the correlation coefficient \(r\approx0\).

Step2: Analyze scatterplot II

Scatterplot II shows a negative - linear trend. So, \(r < 0\).

Step3: Analyze scatterplot III

Scatterplot III shows a positive - linear trend. So, \(r>0\).

Since \(r_{II}0\))

Answer:

B. II, I, III
