Frequency polygons are used to visualise.Select one:a.data distributionb.dispersionc.highs and lows of datad.all of these

Step 1: Break Down the Problem

• The question is asking for the purpose of frequency polygons in data visualization.
• We need to analyze the options provided: a) data distribution, b) dispersion, c) highs and lows of data, d) all of these.

Step 2: Relevant Concepts

• Frequency Polygons: These are graphical representations that show the frequency of data points in a distribution. They are constructed by connecting the midpoints of the intervals (or class) in a histogram.

Step 3: Analysis and Detail

1. Data Distribution: Frequency polygons are primarily used to visualize how data is distributed across different ranges or classes.
2. Dispersion: They can also indicate the spread or dispersion of the data by showing how values are concentrated in certain areas.
3. Highs and Lows of Data: Frequency polygons can help identify peaks (highs) and troughs (lows) in the frequency of occurrence of the data points.

Step 4: Verify and Summarize

• Frequency polygons effectively capture all three aspects: data distribution, dispersion, and the highs and lows of data. Therefore, the best answer is option d) all of these.

Final Answer

d) all of these
