# What is the best measure of central tendency for 2 nominal level variables and why? Question
Analyzing categorical data What is the best measure of central tendency for 2 nominal level variables and why? 2020-10-28
Step 1
Nominal scales are used, without any quantitative significance, to label variables. One might clearly call "labels" the "nominal" scales. A nominal scale represents a group attribute that doesn't have a normal order or rating.
The three basic central tendencies are mean, median and mode.
Step 2
According to the question, there are two nominal levels. it is a kind of categorical variable. Therefore, Mode will be best measure of central tendency for 2 nominal level variables because, the mode can be used for categorical data but it is not possible for the mean and the median. The mode may or may not exist, and the mode may have more than one value.

### Relevant Questions Is the mode the measure of central tendency that is best used with a skewed distribution? True or False
1.The goal of descriptive statistics is to simplify, summarize, and organize data.
2.A summary value, usually numerical, that describes a sample is called a parameter.
3.A researcher records the average age for a group of 25 preschool children selected to participate in a research study. The average age is an example of a statistic.
4.The median is the most commonly used measure of central tendency.
5.The mode is the best way to measure central tendency for data from a nominal scale of measurement.
6.A distribution of scores and a mean of 55 and a standard deviation of 4. The variance for this distribution is 16.
7.In a distribution with a mean of M = 36 and a standard deviation of SD = 8, a score of 40 would be considered an extreme value.
8.In a distribution with a mean of M = 76 and a standard deviation of SD = 7, a score of 91 would be considered an extreme value.
9.A negative correlation means that as the X values decrease, the Y values also tend to decrease.
10.The goal of a hypothesis test is to demonstrate that the patterns observed in the sample data represent real patterns in the population and are not simply due to chance or sampling error. Select the best suitable answer. If none of the choices represents a correct answer, select “Other” and write your own answer. The school cafeteria collects data on students’ juice box selections.
