A recent study reports that older adults who got regular physical exercise (as measured by a pedometer) experienced fewer symptoms of depression, even when tested 2 years later. Following are hypothetical data similar to the results obtained in this study.
a. Calculate the mean and standard deviation for each group of scores b. Based on the statistics from part a, does there appear to e a difference between the two groups? Regular Exercise No regular exercise 1 5 3 4 4 6 3 3 5 5 2 7 3 6 4 6 The deadline for this assignment is 11:59 PM EST on Sunday of Week 1 Title: Re: I have gotten all the questions but this one Post by: skip5284 on Jul 12, 2014 Quote a. Calculate the mean and standard deviation for each group of scores regular mean= (1+3+4+3+5+2+3+4) /8 =25/8=3.125 Stdev= ( ( 1-3.125)^2 +(3-3.125)^2+…..)^.5 = .166 not regular Mean= 5+4+6+3+5+7+6+6/8 =42/8 =5.25 Stdev= ((5-5.25)^2+(4-5.25)^2+…)^.5 =1.199 Quote b. Based on the statistics from part a, does there appear to e a difference between the two groups? Yes. Mean and std dev for no regular group is higherTitle: Re: I have gotten all the questions but this one Post by: habiba on Jul 12, 2014 Hey, see if this helps
