For correctly describing the frequency histogram at the righ

For correctly describing the frequency histogram at the right, you would first point out the most obvious characteristic by saying: the distribution is normal it is platykurtic distribution it is leptokurtic it is skewed left it is mesokurtic for the distribution above which statement would best describe this data from a 10 point quiz from a biology class? The median would be more than the mean the same number of cases for each possible score the range was from 0 to 9 the mean median and the mode would be the same the mean would be more than the median which information is NOT included in ranked data? Each in case in a category is considered identical for that category categories have meaningful order categories have unquantifiable intervals between them categories are mutually exclusive in that one case can be in only one category. The cases in a category are separated from another category by aspecific numeric interval. For the scores on quiz of 2,3,4,4 what would be the mean of the standard score? 4 3.25 0 3.5 1 if the mean score on the biostat examination is 68 points and the standard deviation is 12, what is the exam score of someone whose standardized score was 1.5? 69.5 86 80 84.5 cannot be determined with data provided college students majoring in biology were randomly surveyed about hours studied per week to see if the study habits of students changed with year in school the levels were freshman sophomore, junior, and senior. Major in college ranked variable predictor variable dependent variable extraneous variable constant interval variable
