Circular permutation is the total number of ways in which n distinct objects can be arranged around a fix circle. Practice Problem: What is Q3 for the following data set? Deciles are similar to Percentiles (sounds like decimal and percentile together), as they split the data into 10% groups: The 1st decile is the 10th percentile (the value that divides the data so 10% is below it) The 2nd decile is the 20th percentile (the value that divides the data so 20% is below it) etc! Solution: n = 8. Percentiles: Interpretations and Calculations. So basically we can use deciles and can segregate these funds into best and worst-performing funds for a particular period. Meaning, every decile contains 10% of the data. To find the decile, first order the data from least to greatest. Then, divide the data by 10. This indicates the number of observed values within each decile. Using our previous example, we divide our data into 10 groups, each containing 10% of the data. This can be visualized in the data above. ANSWER TO TRY IT!
