In this course we will learn about the descriptive statistics, correlation and regression.
It refers to methods for
summarizing the collected data. The summaries usually consist of graphs and numbers such as:
- Measures of central tendency,
- Mesaures of dispersion,
- Skewness, and
A correlation coefficient is a symmetric, scale-invariant
measure of association between two random variables. There are two types of correlation:
- Karl Pearson’s coefficient of correlation, and
- Spearman’s rank correlation coefficient
Regression analysis is a mathematical measure of the
average relationship between two or more variables in terms of the original units of the data.
This course will provide you insight to understand univariate and bi-variate data.
