Good evening. I have had a wonderful support with this forum before and thought I would give it another try. I have 10k+ rows of data that includes a client name, score on a specific measure, and the date when the measure was taken. Some clients will only take the measure once, whereas others will take it multiple times. I need data in which clients have completed at least 2 measures, and for clients who have completed more than 2 measures, I need those clients first and last measure. I included an example below for clarity. So I do not need to retain the data for Client A, but I would need the data for Clients B & C. For Client C, however, I only need the data from 12/01/2015 & 5/22/2017 (the oldest and newest). Does anyone know how I can tackle this problem. Thank you for your time!
Example:
Client Measure Score Date Taken
A 5 9/14/2018
B 2 8/01/2016
B 6 10/12/2017
C 1 12/01/2015
C 4 6/13/2016
C 3 5/22/2017
Example:
Client Measure Score Date Taken
A 5 9/14/2018
B 2 8/01/2016
B 6 10/12/2017
C 1 12/01/2015
C 4 6/13/2016
C 3 5/22/2017
