Choose the best statement to summarize the association shown between hat size and IQ in the scatterplot below. Hat Size O The scatterplot does not show a trend that would indicate an association between hat size and IQ scores. O As hat size increases, IQ scores tend to decrease. O As hat size increases, IQ scores tend to increase. Hat size causes IQ to increase.
What is the median?
In this problem, we explore the effect on the mean, median, and mode of adding the same number to each data value. Consider the data set 4, 4, 5, 8, 12. (a) Compute the mode, median, and mean. (Enter your answers to one decimal place.) mode median mean (b) Add 3 to each of the data values. Compute the mode, median, and mean. (Enter your answers to one decimal place.) mode median mean
