Students will review:
This chapter helps students review the concepts in a descriptive statistics unit of a standard research methods in psychology course. Topics covered include:
- Uses of descriptive statistics
- Types of frequency distributions
- Mean, median and mode
- Range, variance and standard deviation
1. What Are Descriptive Statistics? - Definition and Uses
There are several types of descriptive statistics for different purposes depending on the information researchers want to obtain. Learn about the definition and uses of some descriptive statistics, including mean, median, mode, range, standard deviation, and variance.
2. Frequency Distributions: Definition & Types
A frequency distribution is a list of numerical figures represented in a table diagram or histogram that detail how often each value occurs in a set of data. Learn about definition and types of frequency distributions.
3. Mean, Median & Mode: Measures of Central Tendency
In research, measures of central tendency are descriptive statistics that help researchers understand which data is more representative of a data set. Explore the mean, median, and mode. Understand how each measure is calculated, and learn how researchers use each measure to understand samples, as well as the populations that samples represent.
4. Measures of Variability: Range, Variance & Standard Deviation
In research, the variability of a data set helps researchers understand how much the data spreads out around the data set's midpoint, and it also helps researchers compare different sets of data. Explore measures of variability, including range, variance, and standard deviation. Learn how to use the formulas to calculate each measure, and review the definitions of research terms such as population, sample, and parameter.
