he following are true for stem and leaf displays? Check all that apply. O A stem and leaf display shows not only the frequencies of the class intervals but also the scores. Stem and leaf displays are most useful for summarizing and describing data when the data set is relatively large. You can completely regenerate the raw data from a stem and leaf display. A stem and leaf display gives you all the benefits of a histogram.

Select the Observations tab in the left panel of the DataView tool to display the data values. You can sort the values from lowest to highest by clicking the triangle in the column header Variable A. In the table, fill in as many of the empty cells as necessary to construct the stem and leaf display of the data in which the leaves are sorted in ascending order from left to right. Stem and leaf display for Variable A (stem unit = 10s, leaf unit = 1s) 2 2 3 4 The distribution shown in the stem and leaf display is: Negatively skewed O Positively skewed Symmetric
