Answer 1

6, 6, 7, 7, 7, 9 the average deviation of the data is 0.67.

Discussion :

• Average deviation is one branch of statistics.

• The average is the comparison between the amount of data and the amount of data.

• To determine the average deviation, we must first find the average value of data and variance values.

Known:

Data 6, 6, 7, 7, 7, 9

Asked: Average deviation?

Answer:

For example :

x = average data

x = total data / lots of data

x = 6 + 6 + 7 + 7 + 7 + 9/6

x = 42/6

x = 7

Average deviation = Sr

Sr = (| 6 - 7 | + | 6 - 7 | + | 7 - 7 | + | 7 - 7 | + | 7 - 7 | + | 9 - 7 |) / 6

Sr = 1 + 1 + 0 + 0 + 0 + 2/6

Sr = 4/6

Sr = 2/3

Sr = 0.67
