Which measure describes the shape of the normal curve? Ti O a variance Ob. Z-score mean O d. standard deviation In a normal distribution, the mean, mode and median are all equal. O a. Depends on the type of normal distribution Ob. True O c. Depends on some other factors O d. False A z-value tells you the original raw score on which it is based. Ob. the standard deviation of a sampling distribution. O c. how many standard deviations away from the mean a score lies. O d. if the distribution it comes from is normal. What is the value of mean in a standard normal distribution? O a. 1 O b. not fixed
