Correlation coefficient calculator provided at the end of this web page will give you the correlation coefficient of two variables (x) and (y) for which you enter the observations with comma separated. It does not give just only the correlation coefficient of two variables (x) and (y) and also it gives you arithmetic mean (x), mean (y) standard deviation (x) and standard deviation (y). As soon as you enter the observations for (x) and (y) in the boxes provided, click the button "calculate", it will give you correlation coefficient, arithmetic mean (x), mean (y) standard deviation (x) and standard deviation (y).
Apart from the regular calculator, people who study statistics are in need of this correlation coefficient calculator. Because, when people work out lengthy problems, they may not have time to find correlation coefficient for the given two variables (x) and (y). At that time, calculating correlation coefficient would be an additional burden for them in solving lengthy problems. To reduce the burden of those people, we have provided this online calculator here.
When people do preparation of solving word problems on Statistics, they may have to spend time to get idea on "How to solve". In this situation, they would not like to spend time to find correlation coefficient or something like that. Because, when people do word problems on Statistics, they have to do this work separately and they might do some careless mistakes in finding correlation coefficient of two variables. It will definitely disturb the solving of lengthy problem. And also they would not be able to use the regular calculators to find correlation coefficient . By using this online calculator, students will find much time to get idea of solving the word problems.
School students have the topic "Correlation Coefficient" in both school level and college level statistics. They are given some observations of two variables for which they have to find correlation coefficient. They find correlation coefficient as directed in the question.But they are not sure whether the answer they got is correct or incorrect. At that time, they can check the answer they have received is correct or incorrect using this calculator. .
Apart from the advantages explained above, this calculator will also give arithmetic mean (x), mean (y) standard deviation (x) and standard deviation (y).
