ED A.1-- Graphs for Quantitative
On the reassessment for ED A.1, I missed the question because I thought the example was categorical and thus I made a bar graph and pie chart instead of quantitative graphs. The question read "the data below provides the time (in seconds) for a sample of 24 students competing in a cup stacking competition." The problem gave many times (sec) and I grouped the times. By grouping, I originally thought that grouping automatically makes a set of data categorical. I now understand that these times are quantatative and should be shown though the proper graphs.
Categorical variables are characteristis that can't be measured or counted. These variables can be things such as hair color or favorite food. Categorical data is represented through bar graphs and pie charts.
Quantitative variables are values that can be counted, measured, and/or have units. These variables can be things such as lengths of roads or the number of leafs per pile. Quantatative data is represented through histograms, stem and leaf plots, dot plots, and time plots.
