Takeaways

• 📊 Data dispersion is divided into two main measures: range and interquartile range (IQR).
• 📈 The range (J) is calculated as the difference between the maximum (X Max) and minimum (X Min) values in a dataset.
• 📉 The interquartile range (H) is the difference between the upper quartile (Q3) and the lower quartile (Q1).
• 🔢 The quartile deviation (QD) is half of the interquartile range, calculated as (Q3 - Q1) / 2.
• 🔍 To find the range, sort the data, identify the minimum and maximum values, and subtract them.
• 🧮 When calculating quartiles, split the ordered dataset into two halves to find Q1, Q2 (median), and Q3.
• ⚖️ The mean deviation is the average of the absolute deviations of each data point from the mean.
• 📅 For grouped data, the mean and variance are calculated using the midpoints of the intervals.
• 🔄 Variance (S²) measures the dispersion of a dataset, while the standard deviation (S) is the square root of the variance.
• ✅ Understanding these statistical concepts is crucial for analyzing and interpreting data accurately.
