Fill in the blanks. A scatter diagram locates a point in a two dimensional plane. The diagram locates the horizontal axis and the variable on the vertical axis. A. study; explanatory B. explanatory; response C. response; explanatory D. response; study variable on the

lecture(11.12): A large amount of scatter in a scatter plot is an indication that the relationship between the two variables is (a) negative (b) strong (c) weak (d) moderate (e) positive

How do we get these answers? What is the process?

What sort of association (direction, strength, form) did you expect to find, and why?

A real estate company specializing in sales of farms would like to know if their salespeople's sales can be predicted based on the number of years with the company. The years of experience is the explanatory variable and number of sales the predictor. The data is recorded in the tables below. Calculate the intercept (rounded off to four decimals). 1. 3 2 4 4 6 8 8. 9 12 10 10

How to Create a Scatter Plot: 1. Plot each point on the graph, using the values as coordinate points. 2. Draw a line through the points, which shows the general directions of the points. The line should go as much through the middle of all the points as is possible. This is called the line of best fit. The data below shows the temperature and the number of ice creams sold at a particular location on ten different days.
