Significance level, Type I and Type II Error, Confidence interval
In inferential Statistics, we take a value from the sample (a statistic), and infer things about the unknown population parameter. When we use inferential statistics, we can assume that, for instance, the scatterplot we created from a sample represents the overall population. Inferential Statistics can either be point estimations, or interval estimations. In other words, point […]
Summarize data numerically and graphically using R
There are many different ways we can graphically display data. Simple things like bar graphs, pie charts, and stem-and-leaf displays are common place. On the other hand, it would be quicker and more informative to numerically summarize data instead of presenting a visual. Thus, we will talk about both methods to summarize your dataset. Parameters […]
Types of data & Experimental design
It will be important to know the differences in types of data. Because different statistical methods will only work with specific types of data. There are many ways to gather data, and some are better than others. After looking at data types, we will talk about different types of experiments, some sampling methods, and a […]
