Name BA111 Business Math - Statistics Classwork Please show all work for full credit. Place your answers in the table. Below are the test scores for the second history test of a term. Please generate the requested statistics for this data set. Follow the directions to complete this assignment. Test Scores - 60, 75, 90, 95, 91, 95, 67, 85, 80, 87, 88, 90, 75, 80, 90 1. Rewrite the test scores in ascending order: 2. How many test scores (data values) are you working with? 3. Fill in the table. * *Round all answers to tenths* * Mean Median Mode Range Variance Standard Deviation Helpful Hints for finding the statistics 1. Mean - Total up the test scores and divide by the total number of test scores 2. Median - Find the number in the middle of your ascending list in #1. This means that you should have an equal number of data values before and after the number. 3. Mode - Using your list in #1, identify the number or numbers that occur most in your list of data values. 4. Range - Using your list in #1, subtract the lowest test score from the highest test score. 20 900 FA F5 F6 F8 F10 % & 6 8 05. Fill in the table to calculate the variance and standard deviation. Data Value Mean Deviation = (Data value - Mean) Square of Deviation Total = 6. Total the squares of the deviations and enter your sum in the table. 7. Variance = the total from #6 divided by the number of data values minus 1 Variance = 8. Standard deviation is the square root of the answer found in #7. Standard Deviation = FS F6 F7 F8 F10 FII
