Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as p…

Chapter 3.1, Problem 86E

The bar graph shows the ratings of American Idol from season 1 (2002) through season 12 (2013).

Chapter 3.1, Problem 86E, The bar graph shows the ratings of American Idol from season 1 (2002) through season 12 (2013). a.

  1. a. Let x represent American Idol’s season number and let y represent the average number of viewers, in millions. Use a graphing utility to draw a scatter plot of the data. Explain why a quadratic function is appropriate for modeling these data.
  2. b. Use the quadratic regression feature to find the quadratic function that best fits the data. Round all numbers to two decimal places.
  3. c. Use the model in part (b) to determine the season in which American Idol had the greatest number of viewers. Round to the nearest whole number. According to the model, how many millions of viewers were there in that season? Round to one decimal place.
  4. d. How do the results obtained from the model in part (c) compare with the data displayed by the graph?
  5. e. Use a graphing utility to draw a scatter plot of the data and graph the quadratic function of best fit on the scatter plot. Can you see why projections based on the graph had the producers of American Idol looking for a shake-up? No shake-up was found and the show’s final season aired in 2016.
