Advanced Statistics- First Assignment
Here is the results I got for the first assignment.
1)
> set1<- c(10,2,3,2,4,2,5)
> set2<- c(20,12,13,12,14,12,15)
> mean(set1)
[1] 4
> median(set1)
[1] 3
> mode(set1)
[1] “numeric”
> mode(set1)
[1] “numeric”
> mode(set2)
[1] “numeric”
> mean(set2)
[1] 14
> median(set2)
[1] 13
> mode(set2)
[1] “numeric”
2)
> range(set1)
[1] 2 10
> summary(set1)
Min. 1st Qu. Median Mean 3rd Qu. Max.
2.0 2.0 3.0 4.0 4.5 10.0
> var(set1)
[1] 8.333333
> sd(set1)
[1] 2.886751
> range(set2)
[1] 12 20
> summary(set2)
Min. 1st Qu. Median Mean 3rd Qu. Max.
12.0 12.0 13.0 14.0 14.5 20.0
> var(set2)
[1] 8.333333
> sd(set2)
[1] 2.886751
3)
It seems like the summary is different by 10 for the two date sets.
The variance for both data sets are the same. Variance= 8.333333 and st dev= 2.886751.
Noticed the results from set 2 were the same as set 1 just added 10. Did not notice this while looking and writing the data set.
I am not sure why the mode shows “Numeric”, went back to the video but it was also showing “Numeric” for him. Not sure if I am missing something.
