6.7 Probable Error. It is used to help in the determination of the Karl Pearson's coefficient of correlation ' r '. Due to this ' r ' is corrected to a ...

The probable error of the correlation coefficient can be obtained by applying the following formula: Probable Error = 0.6745 ( 1 − r 2) n Here, r = correlation coefficient of ‘n’ pairs of observations for any random sample and N = Total number of observations. Thus, option 2 is the correct answer. Download Solution PDF Share on Whatsapp

As mentioned, probable error is the coefficient of correlation that supports in finding out about the accurate values of the coefficients. It also helps in ...

Definition: The Probable Error of Correlation Coefficient helps in determining the accuracy and reliability of the value of the coefficient that in so far ...

Probable Error

Probable Error use to test the validity of the correlation ... This is because the correlation coefficient is calculated from the sample data and.

The first is the well-known formula for the probable error of the correlation coefficient, r, when it is found by the Pearson product- moment method. It is.

In other words, the probable error (P.E.) is the value which is added or subtracted from the coefficient of correlation (r) to get the upper limit and the lower limit respectively, within which the value of the correlation expectedly lies. The probable error of correlation coefficient can be obtained by applying the following formula: r = coefficient of correlation N = number of observations

306 Probable Error of a Correlation Coefficient to come too low, so that there is a deficiency of cases towards 1 and - 1. This introduces an error into the Standard Deviation of all the series to somie extent, but of course the mean is unaltered when there is no correlation.- The series for

Probable Limit

The probable error of correlation coefficient can be obtained by applying the following formula: r = coefficient of correlation N = number of observations There is no correlation between the variables if the value of ‘r’ is less than P.E. This shows that …

Probable Error of Correlation Coefficient helps in determining the accuracy and reliability of the value of the coefficient that in so far depends on the random sampling. In other words, the probable error (P.E.) is the value that is added or subtracted from the coefficient of correlation (r) to get the upper limit and the lower limit respectively, within which the value of the correlation expectedly lies.
