Which of the following is a primary benefit of using graphs of frequency distributions in statistics?

• A. They eliminate the need for any numerical calculations.
• B. They guarantee that the data is free from outliers.
• C. They make it easier to visualize patterns and trends in the data.
• D. They always show the exact value of every data point.

Answer: (C)

Verified step by step guidance

1. Understand the purpose of a frequency distribution graph: it is a visual representation that shows how often each value or range of values occurs in a dataset.
2. Recognize that graphs help summarize large amounts of data in a way that is easier to interpret than raw numbers alone.
3. Consider the options given and evaluate their validity: eliminating numerical calculations is not true because calculations may still be needed; guaranteeing no outliers is incorrect because graphs do not change the data; showing exact values for every data point is not typical for frequency graphs as they aggregate data.
4. Identify that the main advantage of using graphs of frequency distributions is that they allow us to quickly see patterns, trends, and the overall shape of the data distribution.
5. Conclude that the primary benefit is making it easier to visualize patterns and trends, which helps in understanding the data more intuitively.
