Calculate standard deviation from the following data:
x: 2 4 6 8 10
f: 4 6 8 7 5
The yield of wheat and rice per acre for 10 districts of a state is as under:
District 1 2 3 4 5 6 7 8 9 10
wheat 12 10 15 19 21 16 18 9 25 10
rice 22 29 12 23 18 15 12 34 18 12
calculate for each crop
1. Range
2. Q.D.
3. Mean deviation about mean
4. Mean deviation about median
5. Standard deviation
6. Which crop has greater variation?
7. Compare the values of different measures for each crop.
how does it affect calculation of range ??
