How do I construct a frequency table with grouped data with the following problem? I would also like to know how the frequency scores are calculated from the interval data. Suppose we have collected weights from 100 male subjects as a part of a nutrition study. For our weight data, we have values ranging from a low of 121 pounds to a high of 263 pounds, giving the total span of 263-121=142. Determine reasonable class intervals for a frequency table.
