In an anonymous survey 34 students reported the hours they studied for a statistics final exam. The histogram below shows the results of the survey. Time spent studying 8 4 0-2 2-4 4-6 6-8 8-10 10-12 12-14 14-16 16-18 18-20 20-22 Hours Which statement below is the most accurate description of the center of the distribution? O The median should be used to describe the center, because the values on the horizontal axis can be split exactly in the middle. OThe median should be used to describe the center because, since the data is skewed, the middle outcome may more accurately describe a typícal value in the distribution. O The mean should be used to describe the center because the data is roughly symmetric. O The mean should be used to describe the center because it may produce a decimal value, which is more accurate than the medían.

Answer 1

Yes, Second option is correct. Median should be used to describe the Center. Because the given histogram is Right skewed histogram For Skewed histogram median is best measure of center. Because the mean is affected by extreme values so mean may not be the best measure of center to use in a skewed distribution. For Symmetric histogram (bell shaped) mean is the best measure of centre
