Find online courses made by experts from around the world.
Take your courses with you and learn anywhere, anytime.
Learn and practice realworld skills and achieve your goals.
If you want to learn how to perform the basic statistical analyses in the R program, you have come to the right place.
Now you donâ€™t have to scour the web endlessly in order to find how to compute the statistical indicators in R, how to build a crosstable, how to build a scatterplot chart or how to compute a simple statistical test like the onesample t test. Everything is here, in this course, explained visually, step by step.
So, what will you learn in this course?
First of all, you will learn how to manipulate data in R, to prepare it for the analysis: how to filter your data frame, how to recode variables and compute new variables.
Afterwards, we will take care about computing the main statistical figures in R: mean, median, standard deviation, skewness, kurtosis etc., both in the whole population and in subgroups of the population.
Then you will learn how to visualize data using tables and charts. So we will build tables and crosstables, as well as histograms, cumulative frequency charts, column and mean plot charts, scatterplot charts and boxplot charts.
Since assumption checking is a very important part of any statistical analysis, we could not elude this topic. So weâ€™ll learn how to check for normality and for the presence of outliers.
Finally, we will perform some basic, onesample statistical tests and interpret the results. Iâ€™m talking about the onesample t test, the binomial test and the chisquare test for goodnessoffit.
So after graduating this course, you will know how to perform the essential statistical procedures in the R program. Soâ€¦ enroll today!
