Dthe interval around the sample mean that you expect to contain the population mean

Verified Answer :

The correct answer would be A

Answer:

The correct option is:

Option: A

Aa form of measurement of the average difference between sample values and the sample mean

Step-by-step explanation:

We know that:

The Standard Deviation is a measure of how spread out numbers are.

It is represented by the symbol sigma 'σ '

It is calculated as:

  • Firstly estimating the mean of the data.
  • Then calculating the  deviation of the data points.
  • Squaring the deviations.
  • calculating the mean of the above quantities which is also known as variance.
  • Taking square root of the variance.

Hence, the correct option is:

Option: A.
