)A group of 23 students participated in a math competition. Their scores are below:
Score (points)
20–29
30–39
40–49
50–59
60–69
Number of Students

Would a dot plot or a histogram best represent the data presented here? Why?
Histogram, because a large number of scores are reported as ranges
Histogram, because a small number of scores are reported individually
Dot plot, because a large number of scores are reported as ranges
Dot plot, because a small number of scores are reported individually
What is your choice?
yes i do agree that you ask what her choice was, but i think if she doesn't respond to it then give her two choices to pick from, maybe she is really stuck on this.
your two choices are A or B
A histogram would best represent the data presented here because a large number of scores are reported as ranges (e.g., 20-29, 30-39, etc.) rather than being reported individually. A dot plot would typically be used when the data consists of individual scores, not ranges.
A histogram would be the best way to represent the data presented here.
A histogram is a visual representation of data that groups it into intervals, or bins, and displays the frequency of observations in each interval. In this case, the scores are given in ranges, such as 20-29, 30-39, and so on. With a histogram, you can easily show the frequency of scores within each range and compare the distribution of scores across the different intervals.
In contrast, a dot plot is a visual representation of data where an individual dot represents each data point. Dot plots are more suitable when you have a small number of scores reported individually and want to see their exact values. However, in this case, we have a larger number of scores reported as ranges, so a dot plot would not effectively display the frequency distribution of the scores.
Therefore, a histogram is the appropriate choice in this scenario.
