Question

So, I need help with this or if you could just tell me what they mean by "modes"

Which set of data has 2 modes?

33, 34, 31, 34, 39, 35, 37, 31, 39, 30

31, 34, 31, 34, 39, 35, 37, 31, 34, 35

32, 35, 31, 36, 41, 40, 37, 30, 42, 29

32, 35, 36, 35, 32, 36, 32, 36, 35, 32

Answer 1

The mode is the value that appears most often in a set of data. (By Wiki)
For example, the first set of data 33, [34], [31], [34], [39], 35, 37, [31], [39], 30 have 3 sets of modes

Answer 2

The fastest way to do it is sort the data in ascending order.
