Hi,

I was wondering what the mode be in the following scenarios:

1. No number repeats, as in {1, 2, 3, 4, 5, 6}
is the answer = 'NO MODE' or 'zero'?

2. More than one number has the same frequency, as in {1, 1, 2, 2, 3, 4, 5, 6}

The mode is the number that occurs the most frequently in a data set. For example mode of the set {2, 3, 4, 4} is 4.

Set can have more than one mode, for example set {2, 2, 3, 3, 5} has 2 modes 2 and 3.

If every number in the set occurs an equal number of times, then the set has no mode. For example set {1, 2, 3} has no mode.

Thus:

{1, 2, 4, 8, 8, 8, 9, 10, 10, 10, 11} - has two modes 8 and 10;

{1, 2, 3, 4, 5, 6} - has no mode, since every number in the set occurs an equal number of times;

{2, 2, 4, 4, 6, 6} - has no mode, since every number in the set occurs an equal number of times.

Hope it helps.

1. If all the numbers on the list are different then then is no mode for that list. so 'No Mode'
2. 1 and 2 are the modes are they are frequently repeated numbers in the list

In case 1 there is no mode because the set has equal frequency of each element.

In case 2 1 and 2 both are modes since they both have equal frequency and also their frequency is higher than others.
