Question 1:
1) Scatterplot of the given data:
Stroop test score in X- axis and lunch calories in Y- axis.
2)There are three types of association in scatter plots:
Positive: as one variable increases the other variable also increases in value.
Negative: as one variable increases the other variable decreases in value.
Zero: there is no apparent pattern followed between the two variables.
In the above, there is no apparent relationship seen between the Stroop test score and the lunch calories, hence, it is a zero association.
3) As the dots in the plot are widely spread and not concentrated along a straight line, the association between the two variables is weak here.
4) Outliers are points which are farthest from the regression line; here, the point corresponding to person C may be taken as the outlier.
