  • is the set of numbers
  • is the group name.
  • is either 0 or 1.
    • CORRELATIONDATAANALYSIS(), compares two sets of data.

Description

  • This function shows the correlation data analysis.
  • The Correlation coeffiecient shows the relationship between two continuous variables of each other.
  • In , is the set of numbers .
  • is the group name of correlation and is either "0" or"1".
  • We can use the CORREL function to find the correlation coefficient between two variables.
  • This is also called Pearson's correlation coefficient.
  • It is a measure of the strength of the association between the two variables.
  • The correlation coefficient should not be calculated if the relationship is not linear.
  • Positive correlation indicates that both variables increase or decrease together, whereas negative correlation indicates that as one variable increases, so the other decreases, and vice versa.
