Which of the following statements is the most accurate regarding the interpretation of data using a graphing calculator?

• A. Graphing calculators automatically detect and remove outliers from the data before calculating statistics.
• B. A graphing calculator can provide numerical summaries such as $\mathrm{mean}$, $\mathrm{median}$, and $\mathrm{standard\; deviation}$, but it is important to interpret these values in the context of the data set.
• C. Once you have the numerical summaries from a graphing calculator, there is no need to consider the shape or spread of the data.
• D. The $\mathrm{mean}$ and $\mathrm{median}$ calculated by a graphing calculator will always be the same for any data set.

Answer: (B)

Verified step by step guidance

1. Understand that a graphing calculator is a tool that helps compute numerical summaries such as mean, median, and standard deviation from a given data set.
2. Recognize that graphing calculators do not automatically detect or remove outliers; they simply perform calculations on the data as entered.
3. Remember that numerical summaries should be interpreted in the context of the data, including considering the shape (distribution) and spread (variability) of the data.
4. Know that the mean and median are different measures of central tendency and will not always be the same; their relationship depends on the data's distribution.
5. Conclude that the most accurate statement is that a graphing calculator provides numerical summaries, but it is important to interpret these values within the context of the data set.
