Question

Consider the temperature (in Celsius) of 7 days of a week as 34, 34, 27, 28, 27, 34, 34. Identify the appropriate statistical technique to be used to calculate the following:

Find the standard deviation temperature.

Answer 1

The formula used for calculating Standard Deviation:

σ = `sqrt((sum(x_i - mu)^2)/"N")`

Standard Deviation = `[((2.85)^2 + (2.85)^2 + (4.14)^2 + (3.14) + (4.14)^2 + (2.85)^2 + (2.85)^2)/7]^{1/2}`

= `[10.946]^{1/2} = 3.3084`

The standard deviation of the temperature is 3.3084 C°.
