Which of the following are true for stem-and-leaf displays? Check all that apply. 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 small. Stem-and-leaf displays are most useful for summarizing and describing data when the data set is relatively large. A stem-and-leaf display gives you all the benefits of a histogram. The following data on a quantitative variable named Variable A were collected from a sample of size N = 22. Data Set Sample Data Sample Variables = 1 Observations = 22 Data Values for 50 observations Variables Observations > Form Variable Variable A Type 7 Quantitative Observations Values v Missing 22 0 Numeric Variable Correlation Correlation 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.
