Given a data set, which function on a graphing calculator is typically used to compute the $\mathrm{mean}$ and $\mathrm{standard\; deviation}$ of the data?

• A. The $\mathrm{LinReg}$ function
• B. The $\mathrm{Graph}$ function
• C. The $\mathrm{Table}$ function
• D. The $1-\mathrm{Var} \mathrm{Stats}$ function

Answer: (D)

Verified step by step guidance

1. Understand that to compute the mean and standard deviation of a data set, you need a function that summarizes the data's central tendency and spread.
2. Recognize that the LinReg function is used for linear regression analysis, which models relationships between variables, not for basic descriptive statistics.
3. Know that the Graph function is primarily for plotting data visually, not for calculating statistical measures like mean or standard deviation.
4. Understand that the Table function displays data values in a tabular form but does not perform statistical calculations.
5. Identify that the 1-Var Stats function on a graphing calculator is specifically designed to compute one-variable statistics, including the mean and standard deviation, by analyzing the data set directly.
