Question

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. A stem-and-leaf display gives you all the benefits of a histogram. You can completely regenerate the raw data from a stem-and-leaf display. Stem-and-leaf displays are most useful for summarizing and describing data when the data set is relatively small. The following data on a quantitative variable named Variable A were collected from a sample of size n -22 SetSample Data Sample ariables 1 Observations 22 Data Values for 50 observations Observations Variable 9Type Form Values Missing Variable A Quantitative Numeric Variable Correlaticrn 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 Stem-and-leaf display for Variable A (stem unit . 10s, leaf unit 1s) The distribution shown in the stem-and-leaf display is O Positively skewed O Symmetrical O Negatively skewed

Explanation / Answer

Hello Sir/ Mam

I hope you only want the answer for True/ False part as the data for remaining parts is insufficient.

ALL THE PARTS ARE CORRECT.

(a) Stem and leaf diagram shows both the frequency and the scores.

(b) Stem and leaf diagram is a way to represent data along with data classes and frequency, which is the quality of histogram.

(c) We can completely regenerate the whole data using stem and leaf diagram as we have complete information for doing so in tha data itself.

(d) Stem and leaf diagram is most useful when data is small as presenting large data in stem and leaf make it loose its' core point, easy to dispplay and understand.

I hope this solves your doubt.
