This Excel tutorial explains how to find the percentile of a number from an array using PERCENTRANK.EXC function.
Excel Percentile
Percentile is a statistics term used to describe the Nth observation in a data set after sorting in ascending order. For example, 40th percentile (P40) refers to the approximately 40th data of the 100 data. If the data set is not exactly 100, say 200, we find the location of observation at 40% of total data.
Percentile is commonly used in salary survey to find o...

# Excel T.TEST Function to perform Student’s T Test

This Excel tutorial explains how to use T.TEST Function to perform Independent Sample T Test and Paired-samples T Test.
What is Independent T Test
In statistical inference, we are interested to know whether a small sample comes from a population. To inference using sample mean, when the population standard deviation and population mean are known, we can use Z test to interference the population mean from sample mean.
In reality, we do not have data of the whole population. Without the popul...

# Excel CORREL Function to calculate coefficient of correlation

This Excel tutorial explains how to use Excel CORREL Function to calculate coefficient of correlation.
Coefficient of Correlation
Covariance is a measure of how much two random variables change together. After calculating covariance, we can check the sign whether it is negative or positive. Positive covariance means positive relationship (y increases as x increases), negative covariance means a negative relationship (y decreases as x increases).
In order to measure the strength of relation...

# Excel calculate covariance using COVARIANCE.S and COVARIANCE.P

This Excel tutorial explains how to calculate sample covariance using COVARIANCE.S and calculate population covariance using COVARIANCE.P
Covariance
Covariance is a measure of how much two random variables change together.
The below formula is for calculation of Population Covariance. For Sample Covariance, divide n-1 instead of N.
While σx is denoted as standard variation of x, σxy is denoted as Covariance.
After we calculate the covariance, we can check the sign whether it is ne...

Multiple Regression (Multiple Linear Regression)
Regression analysis is to predict the value of one interval variable based on another interval variable(s) by a linear equation. We draw a random sample from the population and draw the best fitting straight line in order to estimate the population. The straight line is known as least squares or regression...
