What's the mean, median, mode, and range of 1.25 0.5 3.25 0.75 1.75

1.25 0.5 3.25 0.75 1.75

1) arrange the data from smaller to greater:0.5  0.75  1.25  1.75  3.25

2) mean: Add up all data & divide by the number of data
     that is 5==> (7.5/)5 so the mean = 1.5

3) Median is the central value of the data point that is in the middle of the sequence, so the median is 1.25

4) The range is the difference between the largest & the smallest
Range = 3.75-0.5 ==> Range = 3.25

The answers are 20,30,80,180,960,890,1230,4560. on the first row
