Acat gave birth to 4 kittens. three of the kittens had different masses between 147 and 159 kg and one kitten had a mass of 57kg . how will the removal of the kitten affect the mean and median?

they both decrease and the mean decreases more than the median

Step-by-step explanation:

Both the mean and median will increase, but the mean will increase by more than the median.

Step-by-step explanation:

Removing the kitten will increase the median a little bit, because the median shifts from between two data points to the higher of the two data points.

Removing the kitten will increase the mean significantly, because the total weight will decrease by only 57 g , and the number of kittens decreases by 1.

                                                  So

Both the mean and median will increase, but the mean will increase by more than the median.
