This document contains a table of values and bar graph analyzing the frequency and relative frequency of different ranges of values for an ecological lamp. The table shows the class marks, absolute and cumulative frequencies, relative frequencies as fractions, decimals, and percentages, and corresponding degree measures for 4 value ranges between 0 and 20. It then includes a bar graph visually representing the data from the table.
