This article explores solving problems using conditional probability. An event B may depend on event A that has already occurred. Consider the following Venn diagram. [IMAGE] The event A has already happened, so we’re...

In this article we shall explore how to use probability formulae to solve probability problems. Deriving probability formulae We can use the Venn diagram to derive the probability formulae [IMAGE] Let P(A) = a,...

This article explores Venn diagrams. Below is a list of facts you should know when working with Venn diagrams. Events can be represented graphically on Venn diagrams. Venn diagrams are named after Hill born...

In these series of articles we shall explore probability. We shall explore how to solve probability problems using Venn diagrams, using probability formulae, solve problems using conditional probability and how to use tree diagrams....

In this article we shall explore how to compare data sets, deciding which measures of spread and location to use when describing data, and interpreting measures in the context of the question. We use...

In this article we shall explore how to use box plots to represent data. A box plot can be drawn to represent important features of the data. A box plot shows the quartiles, maximum...

In this article we shall cover outliers in statistics An Outlier: Is an extreme value that lies outside the overall pattern of the data

In this article we shall explore the steam and leaf diagrams. A stem and leaf diagram can be used to order or present data given to two or three significant figures. Each observation is...

In this article we shall explore two important measures of dispersion in statistics. The standard deviation and variance for discrete data. Below is a list of notes covered in this article.

This article explores percentiles. Percentiles split the data into 100 parts. A percentile (or a centile) is a measure used in statistics indicating the value below which a given percentage of collected data fall....
