Omdraaien
A categorical variable is a variable that can take on one of a limited, fixed number of possible values, assigning each individual or other unit of observation to a particular group or nominal category.
How is the mean of a dataset calculated?
Omdraaien
The mean is calculated by summing all the values in the dataset and then dividing by the number of values.
What does a scatterplot show?
Omdraaien
A scatterplot shows the relationship between two quantitative variables by displaying data points on a two-dimensional graph.
What is the purpose of a bar chart?
Omdraaien
A bar chart is used to represent categorical data with rectangular bars, where the length of each bar is proportional to the value it represents.
What is an outlier in a dataset?
