You put all the numbers in your data set in a row, and count how many times each one occurs. The one that occurs the most is the mode. No need to overthink, as its very simple :)))
Step-by-step explanation:
EX. 22 45 87 12 45 39 12 67 12
22: appears once
45: appears twice
12: appears three times
87: appears once
39: appears once
67: appears once
12 is our mode as it appears the most in this data set.
