Altering Data Sets: Consider the following sample data 25, 28, 30, 35, 45, 50 Now assume the following changes are made to this data. Comment on what would happen to the mean, median, mode, standard deviation and variance after the changes are made. You do not have to calculate all these values, just determine whether the statistic would increase, decrease, or stay the same. (a) The 25 is replaced by a 10. How would this affect the mean? (Increase, decrease, or no change) .Explain why it would increase/decrease/not change the mean. .How would this affect the standard deviation? .Explain why it would increase/decrease/not change the stanard deviation. (b) The 25 becomes a 20 and the 50 becomes a 55. How would this affect the mean? (Increase, decrease, or no change) .Explain why it would increase/decrease/not change the mean. .How would this affect the standard deviation? .Explain why it would increase/decrease/not change the stanard deviation
