Study Notes
Descriptive Statistics, Significance Levels, and Hypothesis Testing
- Normal Curve: A theoretical distribution of scores, characterized by a bell shape and symmetry, where most scores cluster around the mean. More scores are average or near average than extreme.
- Skewed Distributions: Asymmetrical distributions where one tail is longer than the other, indicating a prevalence of either very high or very low scores.
- Descriptive Statistics: Numerical summaries of data, including the number of cases, measures of central tendency (mean, median, and mode), and measures of dispersion (range and standard deviation). These summarize and represent data to interpret variables.
- Measures of Central Tendency: The mean (average), median (middle), and mode (most frequent) provide the average characteristic of variables, in a dataset.
- Measures of Dispersion: The range (difference between the highest and lowest scores) and standard deviation (measure of how spread out scores are around the mean) demonstrate variability or how dispersed the scores are from the average.
- Frequencies and Percentages: Used to summarize data about a specific variable. Percentage (e.g., 44.1%) signifies a proportion of occurrence compared to a total of occurrences (e.g., 1486).
- Number of Cases (N): The total number of data points or participants in a dataset. A high case number usually means more reliable data points.
- Hypothesis Testing: A technique of drawing conclusions based on the probability that observed data support or reject a research hypothesis (the assertion).
- Significance Levels: The probability of making a Type I error (rejecting a true null hypothesis) is reported, and the commonly accepted standard in communication research is 0.05.
- Null Hypothesis: States that there is no significant relationship or difference between variables; researchers look for evidence to reject this
- Alternative Hypothesis: States that there is a relationship or difference between variables.
- Type I Error: Rejecting a true null hypothesis.
- Type II Error: Failing to reject a false null hypothesis, by failing to find a difference or relationship when it actually exists.
- Statistical Techniques: Significance testing and sampling methods are used to test hypotheses. Using these techniques, researchers establish whether the observed relationship or difference in the data is credible or a matter of chance.
