There is a formula?

Question

I want to know the degree at which a string of numbers is uniform in distance between the numbers.

For example 1,2,3,4 have a distance of 1 between all the numbers and is uniform, so is 10,20,30,40

Now: 10,22,25,40 is not.

Is there a statistical formula to tell me the degree of uniformity of the gaps between numbers in a series?

Answer 1

You can prepare the string of differences. For your last example, it will be 12, 3,15.
Then you obtain the mean and the standard deviation for this last string of values. That will give you the idea of the mean of the gaps and the dispersion of them.

Answer 2

you can add all the numbers and divide them by2.If the answer is a multiple of 5 then they aree uniform else they aree not.
for eg,
1+2+3+4=10
10/2=5 which is a multiple of 5
also
10+20+30+40=100
100/2=50 which is a multiple of 5
but
10+22+25+40=97
97/2=48.5 which is not a multiple of 5
SO 1,2,3,4 & 10,20,30,40 ARE UNIFORM
BUT
10,22,25,40 IIS NOT.
