Positive Correlation

400

If the temperature is 90 degrees about how many visitors should the beach expect?

Between 350-400

375 would be the best answer

400

Dots going down from left to right close together.

400

Line T

Describe the scatterplot below. What is happening in this situation.

As the average daily temperature increase, the number of Beach goers also increases.

(As X increases, Y increases)

500

What type of correlation does a scatterplot show where y tends to decrease as x tends to increase?

Negative Correlation

500

How many hours should someone study to get an A or above a 90% on the exam?

At least 5 hours

500

Draw a scatterplot showing a weak negative correlation

Dots going down from left to right not close together.

500

There is no correlation there is no line of best fit

500

Describe the scatterplot in relation the the situation.

If the student increases the number of study hours their final exam score also increase.

(As X increase, Y increases)
