Question

On a scatterplot what is true about data that shows a weak association?

a. most points are close to trend line
b. only a few points are close so trend line
c. the trend line has positive slope
d. the trend line has negative slope

Answer 1

In a scatterplot with weak association, only a few points are close to the trend line.

Step-by-step explanation:

In a scatterplot, data that shows a weak association means that the points are spread out and do not have a clear trend. Therefore, the correct answer is option b. Only a few points are close to the trend line. This indicates a weak relationship between the variables being plotted.

Answer 2

A scatterplot with a weak association means that b. only a few points are close to the trend line.

Step-by-step explanation:

A scatter plot is a graphical representation of data points on a coordinate plane. It displays individual values for two variables, with each point representing a unique observation. Scatter plots reveal patterns, trends, or correlations between variables, aiding in visual analysis and interpretation.

Thus, this plot represents the relationship between two variables. When the data shows a weak association, it means that there is little or no correlation between the variables. In this case, most points on the scatterplot will be randomly scattered and won't be close to the trend line. So, the correct answer is b. only a few points are close to the trend line.
