Standard deviation (or sometimes standard error, variance, confidence intervals) can be used to help describe a data set. Which of the following statements is/are NOT true? Question 6Answer a. The standard deviation tells you about the variability of the collected data, which is important for conducting statistics b. The mean tells you a lot about the data set; standard deviation isn't as necessary to report because it doesn't have the same units as your measurement c. Multiple and very different data sets can have the same mean; the standard deviation gives you additional and important information about the data as a whole d. Standard error is very sensitive to sample size, as it is used twice in calculations of this value
