The set's data points are:

25, 38, 38, 56, 61, 52, 50, 90, 67, 51, 64, 40

A data set's range is given by range = max-min.

The formula computes the standard deviation.

$s=\sqrt{\frac{\underset{}{鈭�}{x_i}^2-{\left(\underset{}{鈭�}{x}_i\right)}^2/n}{n-1}}$

Because it has a higher maximum and a lower minimum, the non-build up data set has more variation.

As a result, the non-build up data set has more variation.

The set's data points are:

25, 38, 38, 56, 61, 52, 50, 90, 67, 51, 64, 40

A data set's range is given by range = max-min.

The formula computes the standard deviation.

$s=\sqrt{\frac{\underset{}{鈭�}{x_i}^2-{\left(\underset{}{鈭�}{x}_i\right)}^2/n}{n-1}}$

A data set's range is given by range = max-min.

Range

$$\begin{gathered} =90-25 \\ =65 \end{gathered}$$

As a result, the data set's range is 65.

The mean of the given data set.

$$\begin{gathered} \stackrel{炉}{x}=\frac{25+38+38+56+61+52+50+90+67+51+64+40}{12} \\ \stackrel{炉}{x}=\frac{632}{12} \\ \stackrel{炉}{x}鈮�52.6667 \end{gathered}$$

Standard deviation

$$\begin{gathered} 蟽=\sqrt{\frac{\underset{}{鈭�}{\left(x_i-\stackrel{炉}{x}\right)}^2}{n-1}} \\ 蟽=\sqrt{\frac{3174.6667}{21-1}} \\ 蟽鈮�16.98 \end{gathered}$$

As a result, the given data's range and standard deviation are 65 and 16.98, respectively.
