If we collect a large sample of blood platelet counts and if our sample includes a single outlier, how will that outlier appear in a histogram? Choose the correct answer below. OA. The outlier will appear as a tall bar near one side of the distribution. OB. The outlier will appear as the tallest bar near the center of the distribution. OC. The outlier will appear as a bar far from all of the other bars with a height that corresponds to a frequency of 1. O D. Since a histogram shows frequencies, not individual data values, the outlier will not appear. Instead, the outlier increases the frequency for its class by 1.
