**The basic knowledge of statistics**

This data's average amount is,(5+8+3+10+4)÷5=6.

This data's median is,(3 4 D 8 10)→5.

This data's mode is 8.

Of course, the average amount of the deviation is 0.

The deviation of 5 is 6-5=1.

This shows how scattering the amount of data is. If each amount of the data is far from the average, the variance is large amount.

This data's variance is {(6-5)

分散は二乗するため、もしデータの値のそれぞれの単位がｍだったときに分散はuになってしまうので平方根を取る。

This data's standard variance is √6.8=2.6076….
