Exst 2201 Lesson 2.2 Why is it important to look at the shape of a column of data before interpreting any statistics? ️To see if the data is unimodal, symmetrical, and without any exceptions. Why look at a chart to get shape information instead of looking at the data values themselves? ️A chart is needed to summarize the shape characteristic so that we can see it. Match the two meanings below with their appropriate column titles in a frequency table. ️Count of the data values i...
