Question

calculate the coefficient of variation in heights of the student of class given that mean is 162. 6cm and variance is 120 7.69 cm cube​

Answer 1

Answer:

The coefficient of variation in heights of the student of class is 21.37%.

Step-by-step explanation:

Coefficient of variation is used to determine the degree of variation between one data series and another.

It is the ration of the standard deviation (σ) to the mean (μ) of the distribution.

The formula to compute the coefficient of variation is:

$CV=\frac{\sigma}{\mu}\times 100\%$

Given:

σ² = 1207.69

μ = 162.6

Compute the value of CV as follows:

$CV=\frac{\sigma}{\mu}\times 100\%\\=\frac{\sqrt{1207.69}}{162.6}\times 100\%\\=21.37\%$

Thus, the coefficient of variation in heights of the student of class is 21.37%.
