This formula uses 1 Functions, 5 Variables
Functions Used
sqrt - Square root function, sqrt(Number)
Variables Used
t Statistic of Normal Distribution - t Statistic of Normal Distribution is the standard parameter that characterize a sample from population using the sample mean and population mean with respect to the sample standard deviation.
Sample Mean - Sample Mean is the arithmetic average of the individual values in the given sample from a population.
Population Mean - Population Mean is the arithmetic average of the individual values in the given population from which the samples are taking.
Sample Standard Deviation - Sample Standard Deviation is the square root of expectation of the squared deviation of the random variable associated with the given sample from a population from its sample mean.
Sample Size - Sample Size is the total number of individuals present in the given sample in a population under investigation.
STEP 1: Convert Input(s) to Base Unit
Sample Mean: 26 --> No Conversion Required
Population Mean: 22 --> No Conversion Required
Sample Standard Deviation: 3.5 --> No Conversion Required
Sample Size: 20 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
tNormal = (x̄-μ)/(s/sqrt(N)) --> (26-22)/(3.5/sqrt(20))
Evaluating ... ...

P Value of Sample
P Value of Sample = (Sample Proportion-Assumed Population Proportion)/sqrt((Assumed Population Proportion*(1-Assumed Population Proportion))/Sample Size)
Sample Size given P Value
Sample Size = ((P Value of Sample^2)*Assumed Population Proportion*(1-Assumed Population Proportion))/((Sample Proportion-Assumed Population Proportion)^2)
t Statistic of Normal Distribution
t Statistic of Normal Distribution = (Sample Mean-Population Mean)/(Sample Standard Deviation/sqrt(Sample Size))
t Statistic
t Statistic = (Observed Mean of Sample-Theoretical Mean of Sample)/(Sample Standard Deviation/sqrt(Sample Size))
Chi Square Statistic
Chi Square Statistic = ((Sample Size-1)*Sample Standard Deviation^2)/(Population Standard Deviation^2)
Number of Classes given Class Width
Number of Classes = (Largest Item in Data-Smallest Item in Data)/Class Width of Data
Class Width of Data
Class Width of Data = (Largest Item in Data-Smallest Item in Data)/Number of Classes
Expectation of Difference of Random Variables
Expectation of Difference of Random Variables = Expectation of Random Variable X-Expectation of Random Variable Y
Chi Square Statistic given Sample and Population Variances
Chi Square Statistic = ((Sample Size-1)*Sample Variance)/Population Variance

## What is the t test in Statistics?

A t test is a statistical test that is used to compare the means of two groups. It is often used in hypothesis testing to determine whether a process or treatment actually has an effect on the population of interest, or whether two groups are different from one another. There are three t tests to compare means: a one-sample t test, a two-sample t test and a paired t test.
