Problem 14
True/False: When plotted on the same graph, a distribution with a mean of 50 and a standard deviation of 10 will look more spread out than will a distribution with a mean of 60 and a standard deviation of \(5 .\)
Problem 15
Compare the mean, median, trimean in terms of their sensitivity to extreme scores.
Problem 16
If the mean time to respond to a stimulus is much higher than the median time to respond, what can you say about the shape of the distribution of response times?
Problem 17
A set of numbers is transformed by taking the log base 10 of each number. The mean of the transformed data is \(1.65 .\) What is the geometric mean of the untransformed data?
