1) Given a dataset X=[1,2,3,4,5], calculate the mean, variance and standard deviation.

- Given a dataset X=[−5,1,65,4,3,5], calculate the median.
- Without calculating, what is the standard deviation of the dataset X=[1,1,1,1,1]?
- Given a dataset X=[5,4,6,3,4,25,7,6,3,−1,2], calculate the mean and median. Now remove any data points you think are outliers and recalculate the mean and median.
