Standard Deviation Population

What is the standard deviation for the population data given:
5, 10, 7, 12, 0, 20, 15, 22, 8, 2

• 6.89
• 10.1
• 7.26
• 9

If a number is added to a set that is far away from the mean, how does this affect standard deviation?

• increase
• decrease
• stay the same
• both increase and decrease

If a number is added to the set that is in the middle of the data, how does this affect the range?

• increase
• decrease
• stay the same
• both increase and decrease

If a number is added to the set that is near the mean, how does this affect standard deviation?

• increase
• decrease
• stay the same
• both increase and decrease

What is the standard deviation for the sample data given:
5, 10, 7, 12, 0, 20, 15, 22, 8, 2

• 52.7
• 7.3
• 6.9
• 10.1

Determine the standard deviation of the sample?
180, 313, 101, 255, 202, 198

• 65.3
• 71.6
• 5
• 208.2

What is the standard deviation of the population data set?

• 458.0
• 23.10
• 82
• 21.4

If 10 is added to every value in a set of data, what will happen to the value of the median?

• it will increase by 10
• it will decrease by 10
• it will stay the same
• it will both increase and decrease

If 10 is added to every value in a set of data, what will happen to the value of the mean?

• it will increase by 10
• it will decrease by 10
• it will stay the same
• it will both increase and decrease

If 10 is added to every value in a set of data, what will happen to the value of the standard deviation?

• it will increase
• it will decrease
• it will stay the same
• it will both increase and decrease
