Expert Solution & Answer
Explanation of Solution
In statistics central tendency is a central value for a probability distribution. It may also be defined as a center or location of the distribution.
The most important three measures of central tendency are
Mean is the average value of a set of observation.
Median is the middle most observation of a set of observation when all of the scores are arranged in ascending order.
Mode is the value with the greatest frequency of in a distribution.

Based on the data in the attached image, develop a regression model to forecast the average sales of football magazines for each of the seven home games in the upcoming season (Year 10). That is, you should construct a single regression model and use it to estimate the average demand for the seven home games in Year 10. In addition to the variables provided, you may create new variables based on these variables or based on observations of your analysis. Be sure to provide a thorough analysis of your final model (residual diagnostics) and provide assessments of its accuracy. What insights are available based on your regression model?arrow_forwardI want to make sure that I included all possible variables and observations. There is a considerable amount of data in the images below, but not all of it may be useful for your purposes. Are there variables contained in the file that you would exclude from a forecast model to determine football magazine sales in Year 10? If so, why? Are there particular observations of football magazine sales from previous years that you would exclude from your forecasting model? If so, why?arrow_forward
