Q: What are the three primary measures of central tendency mentioned in the text?
- Mean, median, and mode
- Mean, median, and range
- Mean, variance, and standard deviation
- Median, mode, and range
A: Mean, median, and mode

Q: How does the median differ from the mean in terms of sensitivity to extreme values?
- The median is more sensitive to extreme values than the mean.
- The median is less sensitive to extreme values than the mean.
- The median and mean are equally sensitive to extreme values.
- The median does not consider extreme values at all.
A: The median is less sensitive to extreme values than the mean.

Q: Why might a researcher choose to use a box plot instead of a histogram when visualizing data?
- Box plots are easier to create than histograms.
- Box plots provide a clearer view of the frequency distribution.
- Box plots summarize key statistics and potential outliers effectively.
- Box plots can only be used with categorical data.
A: Box plots summarize key statistics and potential outliers effectively.

Q: In what scenario would using the mean be more appropriate than using the median?
- When the dataset contains many outliers.
- When the data is symmetrically distributed without extreme values.
- When analyzing categorical data.
- When the dataset is skewed.
A: When the data is symmetrically distributed without extreme values.

Q: How can understanding measures of variability enhance data analysis in a business context?
- It allows businesses to ignore outliers in their data.
- It helps businesses to understand the average performance only.
- It provides insights into the spread of data, aiding in inventory management and forecasting.
- It eliminates the need for data visualization techniques.
A: It provides insights into the spread of data, aiding in inventory management and forecasting.
