          IQR and standard deviation are both measures of data spread, but they work in different ways. Standard deviation measures the average distance between each data point and the mean, while IQR focuses on the middle 50% of the data distribution.

        • IQR may not capture the entire data spread in cases of extreme skewness

          • By expanding your understanding of interquartile range, you can gain a deeper appreciation for the complexities of data distribution and improve your ability to communicate data insights to others.

        • Consulting online resources and tutorials

          • The increasing demand for data analysis and interpretation has led to a greater emphasis on statistical literacy. As a result, professionals across various industries, from finance to healthcare, are seeking ways to effectively communicate data insights to stakeholders. IQR offers a powerful tool for achieving this goal, allowing users to summarize data spread and identify potential outliers. Its growing popularity is reflected in the adoption of IQR in various sectors, including education and research.

          While IQR is often used with normal data, it can also be applied to non-normal data distributions. However, keep in mind that IQR may not capture the entire data spread in cases of extreme skewness.
