Refer to the Baseball 2005 data, which reports information on the 30 major league teams
for the 2005 baseball season.
a. Select the variable team salary and find the mean, median, and the standard deviation.
b. Select the variable that refers to the age the stadium was built. (Hint: Subtract the
year in which the stadium was built from the current year to find the stadium age and
work with that variable.) Find the mean, median, and the standard deviation.
c. Select the variable that refers to the seating capacity of the stadium. Find the mean,
median, and the standard deviation.
Study the meterial and you will be able to answer the questions.

You do not include the data to answer these questions.
Even so, we do not do your work for you. Once you have answered your questions, we will be happy to give you feedback on your work. Although it might require more time and effort, you will learn more if you do your own work. Isn't that why you go to school?
To answer these questions, you will need access to the Baseball 2005 data, which contains information on the 30 major league teams for the 2005 baseball season. Once you have obtained the dataset, you can follow these steps to calculate the mean, median, and standard deviation for each variable:
a. Team Salary
To find the mean, median, and standard deviation of the team salary variable:
1. Collect the team salary data for all 30 major league teams for the 2005 season.
2. Calculate the mean of the team salary by summing up all the team salaries and dividing by the total number of teams.
3. Calculate the median of the team salary by arranging the salaries in ascending order and finding the middle value.
4. Calculate the standard deviation of the team salary by finding the square root of the variance. The variance is calculated by finding the average of the squared differences between each salary and the mean.
b. Age of the Stadium
To find the mean, median, and standard deviation of the age of the stadium variable:
1. Obtain the year in which each stadium was built.
2. Subtract the year the stadium was built from the current year to calculate the age of each stadium.
3. Collect the age data for all the stadiums.
4. Calculate the mean of the stadium age by summing up all the ages and dividing by the total number of stadiums.
5. Calculate the median of the stadium age by arranging the ages in ascending order and finding the middle value.
6. Calculate the standard deviation of the stadium age using the same process as in step 4.
c. Seating Capacity of the Stadium
To find the mean, median, and standard deviation of the seating capacity variable:
1. Collect the seating capacity data for all the stadiums.
2. Calculate the mean of the seating capacity by summing up all the capacities and dividing by the total number of stadiums.
3. Calculate the median of the seating capacity by arranging the capacities in ascending order and finding the middle value.
4. Calculate the standard deviation of the seating capacity using the same process as in step 4 for the team salary.
By following these steps, you will be able to obtain the mean, median, and standard deviation for each variable in the Baseball 2005 dataset.
