How to filter out data by percentiles?

Question

Let's say i want to filter out all the rows that are above the 70% percentile and below the 15% percentile of a certain variable. How can i do it?

(Just like i can filter out all rows above 50% by using the median filter)

To filter out data by percentiles in JASP for Mac, you can follow these steps:
1. Open JASP and import your data.
2. Click on the Descriptives tab in the upper toolbar.
3. Select your variable of interest from the column of variables on the left.
4. Look for the "Percentiles" section in the top right corner of the Descriptives screen.
5. Enter the desired percentile values. For example, enter 70 and 15 for the 70th and 15th percentiles respectively.
6. JASP will update the statistics and display the corresponding values for these percentiles.
7. To filter out the rows that satisfy the desired percentile criteria, you can right-click on the variable column header and choose "Filter Rows." Then, select "Smaller than or equal to" and enter the value for the 15th percentile and click "OK."
8. Next, right-click on the variable column header again, choose "Filter Rows," select "Larger than or equal to," and enter the value for the 70th percentile. Click "OK."
9. JASP will apply the filters, and only the rows that meet the criteria (above the 70th percentile and below the 15th percentile) will be displayed in the data grid.

I hope this helps!
