Answer #1

A scatterplot is a type of data display that shows the relationship between two numerical variables. Each member of the dataset gets plotted as a point whose (x, y)(x,y)left parenthesis, x, comma, y, right parenthesis coordinates relates to its values for the two variables.

The scatter plot tells us three things:

STRENGTH:strong or weak

FORM-linear or any relationship.

DIRECTION-positive,negative,no correlation.

This helps us to decide the approximate correlation between the two variables under study.

Hence its important to visualize the relationship in a scatterplot before performing a correlation.

Which statement explains why correlation could be 0 even if a strong relationship between two variables existed? Group of answer choices Since the correlation is 0, there is no strong relationship between the two variables; and a scatterplot would be misleading. Correlation can be 0 even if there is a strong linear relationship between the variables. Correlation only measures the strength of the relationship between two variables when the units of the two variables are the same. Correlation does not...
