Here, is the sample mean, σ is the standard deviation, and n sample mean. Here, Z* is the standard normal value, σ is the standard deviation, and MOE is the margin of error. Here, Z* is the standard normal value, σ is the standard deviation, and n is the sample size. Here, x is the original value, is the population mean, and σ is the standard deviation. Statistics TermsĬonvert the original formula into the standard form with the help of z-formula.

Students can use any of them as per their needs. List of Other Important Statistics Formulasīelow, we have mentioned some of the important statistics formulae. Therefore, the standard deviation is 7.92. Now, using the value of the variance, we can calculate the standard deviation. In the above example, we have calculated the variance of the data. Therefore, the sigma (variance) can be calculated as /5 VarianceFind the variance of the data 10,5,-6,3,12. Mode: Find the mode of the data 1,1,2,2,2,3,3,3,3,4,4.Īs 3 is repeated 4 times therefore, the mode of the data is 3. This means 2nd and 3rd terms will be used for median i.e. Now, the median is calculated by Median = /2 therefore, Then, the median can be calculated by writing the data set in ascending order, i.e. This will help you to solve statistical problems. degree? (A) StatisticalĪs you have checked your statistical knowledge, now you can proceed to check the basic statistics formulas. In general, what is the average height of the giraffes? (A) Statistical What is the common area of giraffe ears? (A) Statistical How many days are in the month of July? (A) Statistical How many teeth does Alan have in the mouth?” (A) Statistical At colleges in New York, do football coaches generally get paid higher as compared to tennis coaches? (A) Statistical At a Zoo, do owl monkeys typically weigh more compared to spider monkeys? (A) Statistical In the upcoming paragraphs, we will discuss several statistical formulae that are used for different purposes.īefore proceeding to the basic statistics formulas let’s check whether you can analyze which is a statistical statement and which is a non-statistical statement. Statistics formulas are used by several companies to calculate the report of the people or employees. The methods of statistics are generated to examine the large data and their properties. Statistics is one of the branches of mathematics that is used to study the analysis of data.
