 ## How to calculate discrete probability in Excel

A discrete distribution describes the probability of occurrence of a random variable that can take on only a certain number of values. Common examples for this are the probabilities in a dice roll or getting a certain card in a deck of regular cards. In this guide,... ## Function: PROB

The PROB function is a statistical function that can calculate the probability associated with a given range. The function is useful for calculating the probability for the occurrences having discrete probabilities of an event. In this guide, we’re going to show you... ## How to add error bars in Excel

Error bars are graphical representations of data variability in charts. You can add error bars into your Excel charts to provide a more comprehensive view of the data set. An error bar is usually a horizontal and/or vertical line drawn between lowest and highest error... ## How to calculate variance in Excel

Variance is an important metric in statistics, and it can help you calculate like the risk of an investment. In this guide, we’re going to show you how to calculate variance in Excel. Download Workbook What is variance? Variance is the average of the squared... ## Function: VARPA

The VARPA function is a statistical function that can calculate and return the variance of a population by evaluating text and logical values. Variance provides a general idea of how much data points are spread in a data set, and can be used to calculate the standard... ## Function: VARP

The VARP function is a statistical function calculates and returns the variance of a population. Variance provides a general idea of how much data points are spread in a data set, and can be used to calculate the standard deviation or determine the risk of an... ## Function: VAR.P

The VAR.P function is a statistical function that can calculate and return the variance of a population. This formula was essentially introduced as a replacement for the outdated VARP function. Variance provides a general idea of how much data points are spread in a... ## Function: VAR
