Given the data 11.4, 11.3, 11.2 and 11.1 cm determine the average and its standard deviation using equation

Average   = 11.25 cm

standard deviation = 0.129 cm

Explanation:

The data provided in the question is:

x₁ = 11.4 cm

x₂ = 11.3 cm

x₃ = 11.2 cm

x₄ = 11.1 cm

total number of data points, N = 4

Now, the average is calculated as:

Average =

substituting the values in the above formula we get,

Average   =

Average   = 11.25 cm

Now the standard deviation is calculated as:

standard deviation =

substituting the values in the above equation we get,

standard deviation =

or

standard deviation = 0.129 cm

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
