      While the mean, median, and mode are all measures of central tendency, they vary depending on the distribution of data. The mean is sensitive to extreme values, the median is a better option for skewed distributions, and the mode is useful when there are two or more clusters of values.

    • Median: The middle value when the data is ordered from low to high.

      Common Questions

      Understanding the four friends of statistics opens doors to:

    • Range is the only measure of dispersion, but it's not always accurate.

      • Stay Informed and Take the Next Step

    • Range: The difference between the highest and lowest values in the dataset.

      • Visual inspection and exploratory analysis can help identify skewness. For example, if your data shows a long tail on one side of the distribution, it's likely skewed.
