## Variance in Sampling Distribution of Proportion Solution

STEP 0: Pre-Calculation Summary
Formula Used
Variance of Data = (Probability of Success*(1-Probability of Success))/Sample Size
σ2 = (p*(1-p))/n
This formula uses 3 Variables
Variables Used
Variance of Data - Variance of Data is the expectation of the squared deviation of the random variable associated with the given statistical data from its population mean or sample mean.
Probability of Success - Probability of Success is the probability of a specific outcome occurring in a single trial of a fixed number of independent Bernoulli trials.
Sample Size - Sample Size is the total number of individuals present in a particular sample drawn from the given population under investigation.
STEP 1: Convert Input(s) to Base Unit
Probability of Success: 0.6 --> No Conversion Required
Sample Size: 65 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
σ2 = (p*(1-p))/n --> (0.6*(1-0.6))/65
Evaluating ... ...

## What is Sampling Distribution?

The Sampling Distribution is the probability distribution of a statistic calculated from a random sample drawn from a population. It describes how the value of the statistic is likely to vary across different samples of the same size and shape, drawn from the same population. It is an important concept in statistics because it allows us to make inferences about a population based on sample data. For example, by understanding the sampling distribution of the mean, we can estimate the mean of a population based on the mean of a sample, and calculate the probability that the estimate is close to the true population mean.

## How to Calculate Variance in Sampling Distribution of Proportion?
