What statistical test is used for categorical data?


A one-way analysis of variance (ANOVA)

is used when you have a categorical independent variable (with two or more categories) and a normally distributed interval dependent variable and you wish to test for differences in the means of the dependent variable broken down by the levels of the independent variable.

What descriptive statistics is appropriate for categorical variables?

Descriptive statistics used to analyse data for a single categorical variable include

frequencies, percentages, fractions and/or relative frequencies

(which are simply frequencies divided by the sample size) obtained from the variable’s frequency distribution table.

How do you describe a categorical variable?

In statistics, a categorical variable (also called qualitative variable) is

a variable that can take on one of a limited, and usually fixed, number of possible values, assigning each individual or other unit of observation to a particular group or nominal category on the basis of some qualitative property

.

Which type of variable is used in descriptive statistics?

Descriptive statistics can be used to describe a

single variable (univariate analysis)

or more than one variable (bivariate/multivariate analysis). In the case of more than one variable, descriptive statistics can help summarize relationships between variables using tools such as scatter plots.

How do you summarize categorical variables?

One way to summarize categorical data is to

simply count, or tally up, the number of individuals that fall into each category

. The number of individuals in any given category is called the frequency (or count) for that category.

What are the four types of descriptive statistics?

  • Measures of Frequency: * Count, Percent, Frequency. …
  • Measures of Central Tendency. * Mean, Median, and Mode. …
  • Measures of Dispersion or Variation. * Range, Variance, Standard Deviation. …
  • Measures of Position. * Percentile Ranks, Quartile Ranks.

What are the 5 descriptive statistics?

mean, median, mode, skewness, kurtosis, standard deviation, first quartile and third quartile
