Question

Alice is analyzing the dot plots of the distributions of the ages of children at a local park taken on two consecutive days. What kind of data representation is she using?

A) Bar graph
B) Scatter plot
C) Dot plot
D) Line chart

Answer 1

Alice is using a dot plot, which is a simple and straightforward way to visually represent individual data points on a number line, to analyze age distributions.

Step-by-step explanation:

Alice is using a dot plot to analyze the distributions of ages of children at a local park taken on two consecutive days. A dot plot is a type of data representation where each data value is shown as a dot above a number line. It's an effective way to visualize the frequency of data along a number line and the distribution of values. Other types of graphs like bar graphs, scatter plots, and line charts are used for different purposes and display data in different forms. For example, bar graphs consist of separated bars to compare different groups or categories, scatter plots show the relationship between two different variables, and line charts display data changes over time.
