Which of the following best describes the meaning of a p value for a chi squared score? a) A p value is another way to look at a chi squared score, so a low p value is essentially the same thing as a low chi squared score. b) A low p value means that the data is not likely to show any pattern or correlation. c)The higher the chi squared score, the lower the p value, because high chi squared scores mean the data looks like random data. d)A higher chi squared score means that the data was different from expected, and therefore unlikely to have occurred by chance.
These next questions come after part B. Which of the statements correctly describes the relationship between the mean and median in the histogram of the number of servings of fruit per day claimed by the 7474 seventeen‑year‑old girls? A) The mean and median are about equal because the distribution is right‑skewed. B) The mean is larger than the median because the distribution is right‑skewed. C) The median is larger than the mean because the distribution is right‑skewed. D) There is not enough information to tell us about the relationship between the mean and median in the histogram. (c) In general, you cannot find the exact values of median, quartiles, or mean from the histogram. What is special about the histogram of the number of servings of fruit that allows you to do this?
