Question

1. identify the type of association shown in the following scatterplot and then draw in an approximate trendline.

temperature and no. of ice cream
customers

Explanation:

Step1: Analyze the scatter - plot

Looking at the scatter - plot of temperature (x - axis) and number of ice - cream customers (y - axis). As the temperature (x) increases, the number of customers (y) decreases.

Step2: Determine the type of association

Since the general trend of the scatter - plot is that as one variable (temperature) increases, the other variable (number of customers) decreases, this is a negative association.

Step3: Draw the trendline

To draw the trendline, we try to draw a straight line that best represents the general direction of the data points. We look for a line that has approximately half of the data points above it and half below it.

Answer:

The type of association is a negative association. For the trendline, draw a straight line that slopes downwards from left - to - right, passing through or near the majority of the data points in the scatter - plot.
