# Statistics, Correlation and Regression in Mathematics Free Course

• Description
• Outcome
• Certification
• This free online course is the first of our Upper-Secondary Mathematics suite of courses. It covers mathematical analysis, including univariate statistics and data, bivariate statistics, correlation, regression, residual analysis, non-linear data, and seasonal movements. This course is suitable for students of maths, especially those preparing for examinations. It is also suitable for those looking to refresh their knowledge of Mathematics.

• On completing of this course you will have a good understanding of univariate data, the types of univariate data and displaying this type of data. You will know bivariate data such as dependent, independent variables, parallel boxplots, stemplots, graphical display and much more. You will know how to calculate the mean, median and mode when analysing statistics. You will be able to identify and calculate the interquartile range, standard deviation and boxplots using your calculator. You will know symmetry, calculating a seasonal index, coefficient, regression line, trends and much more. This course will teach you effective exam techniques and tips to help you prepare successfully for your exam.

• All Alison courses are free to study. To successfully complete a course you must score 80% or higher in each course assessments. Upon successful completion of a course, you can choose to make your achievement formal by purchasing an official Alison Diploma, Certificate or PDF.

Having an official Alison document is a great way to share your success. Plus it’s:

• Ideal for including in CVs, job applications and portfolios
• An indication of your ability to learn and achieve high results
• An incentive to continue to empower yourself through learning
• A tangible way of supporting the Alison mission to empower people everywhere through education.
