A study carried out to determine if the average house price has changed since 2015. A random sample of 15 is taken and the prices are recorded. There are two exceptionally high prices that skew the distribution. What is the most appropriate test used for this? eg-Sign Test, T test?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
