Question

The p-value of a statistical test depends on all of the following, except:

Select one:
a. variance
b. mean
c. numbers of samples
d. degrees of freedom
e. median

Answer 1

The correct option is e.

Step-by-step explanation:

p-value is the probability value for a given statistical model, the probability that, when the null hypothesis is true.

For two two samples the formula of test statistics is

`t=\frac{(\overline{x}_1-\overline{x}_2)-(\mu_1-\mu_2)}{\sqrt{(s_1^2)/(n_1)+(s_2^2)/(n_2)}}`

where,

`\overline{x}` is sample mean

`\mu` is population mean.

`s` is standard deviation.

n is sample size.

Variance is the square of standard deviation.

It means variance, mean, numbers of samples is used in calculation of p-value.

Degree of freedom define the shape of the t-distribution that your t-test uses to calculate the p-value.

`d.f.=n_1+n_2-2`

p-value of a statistical test depends on all of the following, except median.

Therefore the correct option is e.
