• IQR is only used for outlier detection, which is not entirely true. IQR can be used for summarizing data distribution and measuring data variability.
  • Sort the data in ascending order.

    • Can IQR be used with categorical data?

  • Find the median (Q2) of the data set.

    • What is the purpose of IQR?

  • Identify the 25th percentile (Q1) and the 75th percentile (Q3) of the data set.
    • Recommended for you

    This topic is relevant for anyone working with data, including:

    IQR is most suitable for continuous data with a moderate to large sample size. However, it can be used with small sample sizes, but with caution.

  • Calculate the IQR by subtracting Q1 from Q3 (IQR = Q3 - Q1).
  • Anyone interested in data analysis and interpretation

    • The IQR is gaining attention in the US due to its ability to provide a robust and efficient way to summarize data. Unlike traditional measures of central tendency such as mean and median, IQR offers a more nuanced understanding of data distribution. This is particularly useful in fields such as finance, healthcare, and social sciences, where data can be skewed or outliers are present. As a result, IQR has become a popular choice for data analysis in various industries.

    No, IQR is used with numerical data only.
