Understanding Correlation Test

It help us to understand whether there is any relation between two variables

 

  • Null Hypothesis (Ho)- >=0.05 means variables are not related
  • Alternate Hypothesis (Ha)- <0.05 means variables are related to each other

 

Correlations: HT, Age

 

Pearson correlation of HT and Age = 0.016

P-Value = 0.703

 

  • P value 0.703 is greater than 0.05 it means there are no relation between HT & Age.

 

Correlations: Typing Speed, HT

 

Pearson correlation of Typing Speed and HT = -0.147

P-Value = 0.001

 

  • P value 0.001 is less than 0.05 it means we have relation between HT & Typing Speed.
  • To check positive or negative relation we have to check Pearson Correlation which is -0.147 it means we have negative relation
