Question

question 9. which data displays below allow you to see if a data value was repeated more than once? select all that apply. a. histogram b. bar graph c. box plot d. stem - and - leaf plot e. circle graph f. line plot

Explanation:

• Stem - and - leaf plot: Each data value is shown, so repeated values are visible. For example, if the stem is \(2\) and the leaves are \(3,3,5\), we can see that \(23\) is repeated.
• Line plot: Data points are plotted as marks (e.g., dots) on a number line. If there are multiple marks at the same value on the number line, it indicates repetition.

• Histogram: Groups data into intervals (bins). It shows the frequency of data within intervals, but not individual data values, so we can't tell if a specific value is repeated.
• Bar graph: Compares categorical data. It shows the count of each category, not individual data values within a category (unless the category is a single value, but it's not designed to show repetition of individual data points in the same way as stem - and - leaf or line plot).
• Box plot: Shows the five - number summary (minimum, first quartile, median, third quartile, maximum). It does not show individual data values, so no information about repetition.
• Circle graph (pie chart): Shows the proportion of each category. It does not show individual data values, so no information about repetition.

Answer:

D. Stem - and - leaf plot, F. Line plot
