increase . please mark brainliest

The changes in the value of the report would lead to a decrease in the values of the mean and standard deviation. The interquartile range and the median would not change.

Which values would change?

Mean is the average of a set of numbers. Standard deviation is used to determine how the values in a group differs from the mean of the values in the group. It is a measure of variation.

The mean would change because the sum of the numbers would reduce, this would affect the mean. The variation in the data reduces. This would reduce the standard deviation.
