Chapter 12: Q. 17 (page 715)

Does the scatter plot appear linear? Strong or weak? Positive or negative?

Short Answer

Expert verified

The plot is linear with strong and the correlation is positive

Step by step solution

01

Given Information 

Given in the question is a graph,

02

Explanation

The points on a scatter plot clearly represent a straight line. Therefore, the plot is linear.

The nearer the information points reach to create a straight line when plotted, the more increased the correlation between the two variables, the stronger the connection. If the data points create a straight line proceeding from near the source out to high y-values, the variables are said to have a positive correlation.

Here, The points of the graph are very dense and there is no outlier. So the scatter plot is stronger.

According to the graph, it is in increasing order. Therefore, the correlation is positive.
