Study Notes
Quantitative Analytical Methods
- This course covers advanced quantitative analytical methods.
- A presenter, Dr. Emmanuel Jay D. Dima, RN, RM, LPT, is delivering the lecture.
Correlation
- Correlation uses statistical analysis to describe the relationship between two variables.
- Correlation results do not establish a causal relationship.
Analysis of Variance (ANOVA)
- ANOVA analysis determines if differences in means or averages of two data categories are statistically significant.
- Example: Comparing grades of students who attend tutorials versus those who don't.
Regression
- Regression shares similarities with correlation by showing relationships between variables.
- Unlike correlation, regression provides broader results and assesses if one variable can predict another.
- For instance, music during review can predict concept learning.
- Regression, like correlation, cannot establish cause-and-effect.
Statistical Methods
- Statistics involves collecting and analyzing numerical data.
- Mathematical operations (addition, subtraction, multiplication, division) are used.
Statistical Methodologies (Descriptive Statistics)
- Descriptive statistics summarize data features (mean, median, mode, standard deviation).
- This method describes data placement within a dataset, and the distribution or extent of data, and potential correlations/regressions among variables.
- Descriptive statistics do not describe the population.
Statistical Methodologies (Inferential Statistics)
- Inferential statistics focuses on drawing conclusions, generalizing, and predicting from samples.
- It aims to understand features of a larger population using a sample.
- Inferential statistics use complex mathematical calculations and hypotheses testing.
Types of Statistical Data Analysis
- Univariate analysis examines single variables.
- Bivariate analysis investigates relationships between two variables (independent and dependent).
- Multivariate analysis explores relationships between multiple variables.
Statistical Methods of Bivariate Analysis (Correlation/Covariation)
- Correlation describes and measures the strength/significance of a linear relationship between two variables.
- Covariation is a statistical term measuring relationships between random variables.
Statistical Methods of Bivariate Analysis (Cross-Tabulation)
- Cross-tabulation (crosstab/contingency table) is a matrix displaying frequency and percentage distributions.
- It shows the relationship between two variables and the effect one has on the other.
