Q.Assertion (A) : When sample size is small and/or data are badly skewed (so that assumption of normality is doubtful) parametric methods are not applicable. Reason (R) : In parametric tests we can assume that scores upon which our statistics are based are normally distributed in the population. Code :
Correct answer: Both (A) and (R) are correct and (R) is the correct explanation of (A)
Explanation
Parametric tests are applied when information about the population is completely known and data is normally distributed. When sample size is small and/or data are badly skewed parametric methods are not applicable.
