Learners enrolled: 622
This is an elementary course on statistics and here we will begin with basics of statistics. The statistics are needed so that we can formulate our argument laded with substantial data input. The logic of argument may be supported by empirical data. The empirical data has scientific value because it can be retested, validated and verified. Therefore, the knowledge of statistics with its techniques of sampling as well as data collection will be very helpful tools for students. 

In this course, you will learn different types of variable and their effect on each other which are captured through numerical data and interpretation of same is done statistically.

The descriptive data represented through graphs will enable students to understand various concepts of psychology more clearly along with their numerical magnitude.
Learning about probability and normal probability distributions will help you understand nature of psychological attributes and how those are distributed in populations.

Analysis of variability would enhance your learning on how much variance one variable has to explain on other variables. The correlation will also indicate degree of associations among variable and thus would propel to investigate the causation among those variables. 

The completion of this course will infuse motivation and confidence on numerical interpretations of research analysis to the students.
