Check their calculations for Post 1 and Post 2. If any of the answers are not correct, tactfully identify the error and show the work correctly. Check all calculations carefully because if you miss a mistake it will affect your grade. Consider your classmate's Post 1 and Post 2. Which calculation, the mean, median, or mode, do you feel is the best representation of their data? Or, perhaps you feel each calculation represents the data well?? Explain your point of view using statistics to back it up. A sentence that interprets the meaning of the standard deviation your classmate calculated.

A sentence that interprets the meaning of Q1, Q2, and Q3.

Standard Deviation X S= 3.5 To find the standard deviation all you do is put a square root sign over the s ^ two and the solution from the variance problem so then you get the standard deviation.

For the variance I got 13.38. With the variance value changed, I also got a different answer for your standard deviation which is now 3.66. 1. I believe the mean is the most important calculation of the data. It is the average height and if one wanted to look at a list of 10 peoples height, the mean is just one number to see the average height X that they could easily compare themselves to. 2. Standard deviation measures the spread of the data about the mean value. Looking at the standard E deviation, one can easily see how much people tend to vary off of the mean. In other words, you can see how much a person is on average taller or shorter than the mean. 3. Q1 is 64, Q2 is (65+68)/2=66.5, Q3 is 70. 25% of people fall at or below 64inches and puts them in Q1. 50% of people fall below or at 66.5 inches and puts them in Q2. 75% of people fall below or at 70 inches and puts them in Q3. 0 5 6:53FSA Log In | Federal Student Aid X *Homework Help - Q&A from Or x | @ Grammarly X Content X Paraphrasing Tool | QuillBot A X + X C A faytechcc.blackboard.com/ultra/courses/_37370_1/cl/outline UU.U To find the mean all you do is add all the x values (the heights) and then divide it by the number of classes (n) which is 10. X 3. Median 65+68/ 2 = 66.5 4. Mode = 64 and 70 The mode is the number that appears the most throughout your data set. 5. Range 72 - 61 = 11 The range is found by taking the maximum data and subtracting it by the minimum data entry. 6. Variance S 2= 12.63 To find the variance you have to first find the mean of the data set which is 66.6 X then you have to find the deviation of each entry which is found by subtracting the x value by the mean. then you square each deviation by raising that number that you got previous to two so it would be the x value minus the mean ^ two E then you would add to get the sum of squares and then take that number and divide it by n minus one. 7.
