The Pearson's coefficient of skewness of X variable from a data set is +2.7. Some interpretation can be made about the data:
Mean equal median
More than 50% of the data has values more than the mean
Less than 50% of the data has values more than the mean
Less than 50% of the data has values more than the median More than
50% of the data has values more than the median
which one are correct
Homework Answers
If the frequency curve of the data is not equally distributed both sides, then it is known as the skewed data or curve.
the value of skewness lies between -3 and +3.
If tails lies more in the direction of the left, then it is known as the negatively skewed.
Mode> median > mean
If tails lies more in the direction of the right, then it is known as the positively skewed.
Mean> Median > mode
The Pearson's coefficient of skewness of X variable from a data set is +2.7.
Since the given value of the skewness is +2.75 which is positive, it means mean is greater than the mode and median. Hence it can be said that Less than 50% of the data has values more than the mean.
Hence option third is the correct answer.
