Work Step by Step
a. Appropriate Measure of Central Tendency
Because these data are nominal (i.e., they consist of category names/initials), the only appropriate measure of central tendency is the mode—the category that appears most frequently. From the frequency distribution, G (Gandhi) appears most often, so the mode is G.
b. Statistic or Parameter?
Usually, we call a value calculated from data a statistic if it comes from a sample. A parameter is a measure for an entire population. Here, the political science student traveled on every street in one precinct (which might still be considered just a sample of all precincts). Most often in such studies, we treat the result as a statistic because the precinct is typically only a portion of a larger population of interest.
c. Sentence of Interpretation
“In this precinct, the most frequently observed yard signs were for Gandhi, indicating that Gandhi was the mode among the five candidates.”
