What is deviation?

And what is the definition of frequency distribution & how would I solve a problem in 8th grade math with this problem...My child is asking about this problem she has in an 8th grade book.
Given the following numbers 2,2,3,6,1,9,4,2,5,7,6,8,6,
What is the frequency of distribution of 2?.

Count the number of 2's. There are three 2's.

I THINK IT IS 1 BECAUSE IT IS THE LOWEST NUMBER AND THERE IS ONLY ONE

Yes it is 1 /\

Deviation is a statistical term that measures the amount of variation or dispersion in a set of data points. It tells us how different each data point is from the mean (average) of the data set.

To calculate the deviation, you need to follow these steps:
1. Find the mean of the data set by adding up all the numbers and dividing by the total count. In this case, the sum of the numbers is 2+2+3+6+1+9+4+2+5+7+6+8+6 = 61. The count of numbers is 13. So the mean is 61/13 = 4.6923 (rounded to four decimal places).
2. For each individual number, subtract the mean from it. This gives you the deviation for that number.
3. To find the deviation for 2 in this frequency distribution, follow the second step and subtract the mean (4.6923) from 2. The deviation would be 2 - 4.6923 = -2.6923 (rounded to four decimal places).

Now, let's talk about frequency distribution. Frequency distribution is a way to organize and display data to show how often the different values occur. It helps us understand the distribution patterns and frequencies of data points within a data set.

To solve your problem regarding the frequency distribution of 2, you need to count how many times the number 2 appears in the given data set.

In the provided data set: 2, 2, 3, 6, 1, 9, 4, 2, 5, 7, 6, 8, 6, the number 2 occurs three times.

Therefore, the frequency distribution of 2 in this data set is 3.
