At least one of your answers is incorrect. To construct a frequency distribution with a given first lower class limit and class width, list the other lower class limits. Do this by adding the class width to the first lower class limit to get the second lower class limit. Add the class width to the second lower class limit to get the third lower class limit, and so on. List the lower class limits in a vertical column and then determine and enter the upper class limits. When constructing a frequency distribution, be sure the classes do not overlap. Take each individual data value and put a tally mark in the appropriate class. Add the tally marks to find the total frequency for each class. Technology can also be used to construct a frequency distribution. Remember to type whole numbers
