Here is the data from the post-treatment measurement of memory after 3 months of “ginko biloba therapy.” The scores represent number of words recalled on a test that required memorization of random lists of nouns.

84, 70, 94, 73, 81, 88, 99, 75, 63, 91, 85, 72

Do the following statistical calculations: Mean, Median, Mode, Range, Variance and Standard Deviation

Create a proper graphical display for the above data (measurement of memory performance).

Expert Solution

Mode is nothing but most of repeated numbers in the data set. Here in the example there is no repeated numbers. So there is no mode available.

After 3 months of endurance training John (who you may remember from Applied Essay 3 is not very fit; initial VO2 max of 35.0 mL·kg-1·min-1) could not believe how much further he could run without having to stop. Initially he could barely get around the track once…now he can run 12 laps of the track (3 miles) at a pace he could barely maintain for 1 lap a few months earlier. Although the training likely increased his VO2 max (much...

The data here (data204.dat) is the LOS in months and wages for 60 women who work in Indiana banks. Wages are yearly total income divided by the number of weeks worked. We have multiplied wages by a constant for reasons of confidentiality. (a) Plot wages versus LOS. Consider the relationship and whether or not linear regression might be appropriate. (Do this on paper. Your instructor may ask you to turn in this graph.) (b) Find the least-squares line. Summarize the...
