Introduction

percentile is a measure used in statistics indicating the value below which a certain percent of observations in a group of observations fall. The term percentile and the related term percentile rank are often used in the reporting of scores from standardized tests, such as the SAT. For example, if a particular score is at the 86th percentile, it is equal to or better than 86 percent of the scores in the data set and equal to or worse than 14 percent. Percentiles are also used frequently in non-parametric statistics.

Steps to Find the Percentile for the Data Value Data Set

In order to find the percentile for the data value data set 55 38 30 66 67 68 44 data value 55, you will first need to order the data from smallest to largest. This will give you the following data set: 30, 38, 44, 55, 66, 67, 68. Next, you will need to find the median of the data set, which is 55. The percentile is then calculated by taking the median and dividing it by the total number of data points, which is 7. This gives you a percentile of 55/7, or 7.85%.

Arrange the data set in ascending order

To find the percentile for the data value data set 55 38 30 66 67 68 44 data value 55, you will need to first arrange the data set in ascending order. The numerical order for this data set would be as follows:

30, 38, 44, 55, 66, 67, 68

Find the median of the data set

The median of the data set is 55.

Find the percentile for the data value 55

To find the percentile for the data value 55, first sort the data set from smallest to largest. The data set is now:

30, 38, 44, 55, 66, 67, 68

To find the percentile, take the number of values in the data set (7) and multiply it by the percentile you are looking for (55). This gives us a value of 3.85. We round this up to 4 since we can’t have a partial value. This tells us that we need to find the 4th value in our sorted list – which is 55. Therefore, the percentile for 55 is 50%.

Conclusion

After finding the percentile for the data value data set 55 38 30 66 67 68 44 data value 55, we can see that it is in the 60th percentile.
