Section 2.1, Frequency Distributions and Their Graphs
www.math.utah.eduSection 2.1, Frequency Distributions and Their Graphs The main characteristics we will use to describe a data set are its center, its variability, and its shape. One way to see patterns in data is to make a graph. In this section, we will look at 3 ways to graphically summarize data: frequency distributions, frequency histograms, and a cumulative
RESEARCH METHODS 1: FREQUENCY DISTRIBUTIONS
users.sussex.ac.ukHow can we compare frequency distributions when they are based on different totals? The solution is to turn our "raw" frequencies into relative frequencies. To turn a raw frequency into a relative frequency, divide the raw frequency by the total number of cases, and then multiply by 100. Thus (25/50)*100 = 50%, and (25/100)*100 = 25%.

uca.eduWhat we have in Figure 10.1 are two frequency distributions of yards per play. A frequency distribution shows the number of times each score (in this case, the number of yards) is obtained. We can tell at a glance that these two distributions are markedly different. A pass play is a study in contrasts; it leads to extremely variable outcomes.
