Which statistical analysis would NOT be used in a quantitative study?

Content analysis is the correct choice, as it is primarily a qualitative research method rather than a quantitative statistical analysis. It involves systematically examining and interpreting communication content—such as text, audio, or visual material—to identify patterns, themes, or biases. This method is focused on understanding the meaning and context behind the data rather than employing statistical techniques to analyze numerical data.

In contrast, regression analysis, ANOVA, and t-tests are all statistical methods used in quantitative research. Regression analysis explores the relationships between variables by predicting the value of a dependent variable based on one or more independent variables. ANOVA (Analysis of Variance) tests for differences in means among three or more groups, helping researchers determine whether there are statistically significant effects. T-tests compare the means between two groups to see if they are statistically significantly different from one another.
