Steps Open the Heart Rate Dataset in Excel Using the classification of variables from Unit 1 assignment as qualitative, quantitative discrete, or quantitative continuous, match each of the 3 variables to the most appropriate graph type. (For example, qualitative data can best be displayed with a pie chart or bar graph; continuous numerical data can best be displayed using a histogram) Use the graphing functions in Excel to create an appropriate graph of the data for each variable.
