TIMELINE OR LINE GRAPH The Timeline Graphs necessary for this exercise are also in Public Files/Mod1 A timeline or line graph shows trends over time. This study examines whether there is any relationship between the season of the year and suicide rates. These two line graphs show rates per 100,000.This study was based on data from Hong Kong only for the years 1980 to 1994. Line Graph images 1.5 1.0 Figure 1.

The scatter plot shows the relationship between the average number of times, t, a person goes to a movie theater per month and the person's age in years, a, for 9 people. A trend line that passes through the point (5, 20) is also shown. Age 90 80 70 60 50 40 30 20 10 Going to the Movie Theater 0 1 2 3 4 5 6 7 8 Movie Theater Visits per Month What is the equation for the trend line?
Linear Regression Problem (See the data table) Please refer to the table on the last page to answer this problem The table displays the average global temperature in degrees celcius relative to the year 2000 in five year intervals. What relationship are you interested in studying? Identify the independent and dependent variables. How many data points were collected? Was sampling conducted? Draw a bubble diagram showing the relationship between the variables, include the effects of a confounding variable on your diagram.
Chapter 11 Worksheet on Regression Name Consider an experiment designed to estimate the linear relationship between the percentage of a certain drug in the bloodstream of a subject and the length of time it takes the subject to react to a stimulus. In particular, the researchers want to predict reaction time based on the amount of drug in the bloodstream. Give a practical interpretation of the slope. Give a practical interpretation of the coefficient of correlation. What percentage of the sample variation in y can be explained by x in the simple linear model?
