In this course, we will recap the Grade 11 content that is also tested in Grade 12. After revising calculation of the mean and standard deviation, we will focus on cumulative frequency and the graph of cumulative frequency, the ogive. We will also revise the five-number summary, box-and-whisker plots, skewness of data and outliers.
We then focus on scatter plots and learn how to calculate the equation of the least squares regression line. We will also learn how to calculate the correlation coefficient. We end the course by examining the types of questions we would expect to see in the trial exams as well as the final NSC examinations.
This course takes the basics one step further to provide some extended examples and questions for those learners who enjoy a challenge. See you there!
