Final answer:
The circled section in the stemplot represents that eight boys scored 12 marks on it, showing the usefulness of stemplots in quickly identifying data distribution. The correct pint is • Eight boys scored 12 marks on it.
Step-by-step explanation:
The circled section in the stemplot appears to indicate a particular score range for the boys in the class. The stemplot is a visual representation of the distribution of scores, and the section circled typically represents a group of data points that share a common stem value, which in this context refers to the tens place of the scores.
From the given information, we deduce that the correct interpretation of the circled section is that eight boys scored 12 marks on it.
Stemplots provide a convenient way to quickly see the distribution of data in a set, including the most frequent scores or the central tendency, like the mean or median score. Stemplots, histograms, and bar graphs are all ways to visually display statistical data, making it easier to analyze.
