The file SAT Excel data lists the average high school student scores on the SAT exam by state. There are three components of the SAT: Critical reading, math and writing. These components are listed in Excel. Also, the sum of all 3 components (The Combined column) is listed. The percentage of all potential students who took the SAT is listed by state. Use Excel to help you answer the following questions. Find the mean, median, and mode for each of the numerical variables. For each of the numerical variables, which is the most appropriate measure of central tendency and explain why.
Solutions
Expert Solution
As the data is not given, I have taken at random 20 students and generated random numbers for their marks.
Hence it is evident that as the data in writing is highly dispersed, median is the best measure here to avoid the effect of the outliers. Elsewhere mean is the best measure to determine the central tendency of the variables.
To have the best answers, you must submit the data file along with the question.

--------------------------------------------------
Boys' midterm score 70 20
Boys' final score 65 23
girls' midterm score 75 20
girls' final score 80 23
The correlation coefficient between midterm score and final
score for the boys was about 0.70; for the girls, it was about the
same. If you take the boys and the girls together, the correlation
between midterm...
