Question

When an observation in a data is abnormally more than or less than the remaining observations in the data,does it affect the mean or mode or median why

Answer 1

Dear student
only mean will change as mean is the average of all the data and it depends on each observation. Mode will not change as mode means most frequently observed value which is not depend on one value. median will also not change as median is middle value and again not depend on any abnormal value.
