How can the mean and other distribution averages be calculated using a frequency table?

• A. By applying the median formula
• B. By entering values into list 1 and 2 into stat mode on a GDC
• C. By summing all values directly
• D. By calculating the mode of the frequency table

Answer: (B)

Using a frequency table, the mean and other measures of central tendency can be effectively calculated by utilizing a graphical display calculator (GDC) in stat mode. This method involves entering the data values in one list and their corresponding frequencies in another list. When you input data this way, the GDC can automatically interpret the frequency of each value, allowing it to compute the mean directly, which is a weighted average considering how often each value appears. Moreover, the calculator can also facilitate finding the median and mode, providing a comprehensive statistical analysis of the dataset presented in the frequency table. This approach is particularly advantageous as it minimizes manual calculation errors and streamlines the process of analyzing larger datasets. Thus, using a GDC in stat mode leverages technology to efficiently and accurately perform these calculations.
