PSYCH 1X03 Study Guide - Quiz Guide: Pie Chart, Central Tendency, Frequency Distribution
Document Summary
Statistics allow one to summarize, interpret, and present the data we have collected. Descriptive statistics presents information that gives an overall idea of the results of the experiment; mean, median, mode. Visual summarizations of data (pie chart, bar graph ); type of graph used to report the number of times groups of values appear in a data set: x-axis = bins. Frequency distribution type of graph illustrating the distribution of how frequently values appear in the data set: shows data given every possible outcome of an event. In most cases, higher values are more frequent in the experimental group: a smooth curve that connects the peaks of each bar in a histogram. Normal distribution a distribution with a characteristic smooth, symmetrical, bell- shaped curve containing a single peak: shows data for a given measure. Tells us where a data set is centered; average value of a data set.
