Variance in Geometric Distribution Solution

STEP 0: Pre-Calculation Summary
Formula Used
Variance of Data = (1-Probability of Success)/(Probability of Success^2)
σ2 = (1-p)/(p^2)
This formula uses 2 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.
STEP 1: Convert Input(s) to Base Unit
Probability of Success: 0.6 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
σ2 = (1-p)/(p^2) --> (1-0.6)/(0.6^2)

6 Geometric Distribution Calculators

Geometric Distribution
Go Geometric Probability Distribution Function = Probability of Success in Binomial Distribution*Probability of Failure^(Number of Independent Bernoulli Trials)
Standard Deviation of Geometric Distribution
Go Standard Deviation in Normal Distribution = sqrt(Probability of Failure in Binomial Distribution/(Probability of Success^2))
Variance of Geometric Distribution
Go Variance of Data = Probability of Failure in Binomial Distribution/(Probability of Success^2)
Variance in Geometric Distribution
Go Variance of Data = (1-Probability of Success)/(Probability of Success^2)
Mean of Geometric Distribution given Probability of Failure
Go Mean in Normal Distribution = 1/(1-Probability of Failure in Binomial Distribution)
Mean of Geometric Distribution
Go Mean in Normal Distribution = 1/Probability of Success

Variance in Geometric Distribution Formula

Variance of Data = (1-Probability of Success)/(Probability of Success^2)
σ2 = (1-p)/(p^2)

What is Variance and the importance of Variance in Statistics?

Variance is a statistical tool used to analyze a statistical data. The word Variance is actually derived from the word variety that in terms of statistics means the difference among various scores and readings. Basically it is the expectation of the squared deviation of the associated random variable from its population mean or sample mean. Variance ensures accuracy as more Variance is considered good as compared to the low Variance or absolutely absence of any Variance. Variance in statistics is important as in a measurement it allows us to measure the dispersion of the set of the variables around their mean. These set of the variables are the variables that are being measured or analyzed. The presence of the Variance allows a statistician to draw some meaningful conclusion from the data. The advantage of Variance is that it treats all deviations from the mean as the same regardless of their direction.
