WebHere are the directions for drawing a box plot: Compute Q1, Q2 and Q3. Also, compute the interquartile range IQR = Q3 - Q1. Example: Suppose that the dataset consists of these hypothetical test scores: 5 39 75 79 85 90 91 93 93 98 Q1 = 75, Q2 = 88, Q3 = 92. IQR = 93 - … WebCreate a data set with a median below 2 and a mean between 2 and 4. Specify a sample size and then select Simulate to generate a variety of data sets. Add values to the data set by repeatedly selecting various locations above the horizontal axis of the plot. Change individual data values by selecting the points in the graph. song little boxes ticky tacky

They are calculated as: Upper fence = Q3 + (1.5*IQR) Lower fence = Q1 – (1.5*IQR) where IQR stands for “interquartile range” and represents the difference between the 75th percentile and 25th percentile in a dataset.

Using StatCrunch, construct a contingency table for these data, computing both row and column percentages, with totals and all labels for each of the four cells and totals.
