Understanding Measures of Central Tendency

What is the primary purpose of measures of central tendency in data analysis?

• To summarize a set of data by identifying the central point

• To identify the highest and lowest values in a dataset

• To calculate the variance and standard deviation

• To determine the correlation between two variables

Which measure of central tendency is most affected by outliers?

• Mean

• Median

• Mode

• Range

When is the median a more appropriate measure of central tendency than the mean?

• When the dataset is skewed or contains outliers

• When the dataset is normally distributed

• When the dataset contains nominal data

• When the dataset has no repeated values

What is the mode in a dataset?

• The value that appears most frequently

• The average of all data points

• The middle value when data is ordered

• The difference between the highest and lowest values

In which scenario is the mode particularly useful?

• Understanding the most common category or value

• Calculating the average of a dataset

• Finding the middle value in a dataset

• Determining the spread of a dataset
