Well, those are frequencies, which tell you how many of each number there are. So there are two 1’s, five 2’s, eight 3’s, etc. The total number of observations (n) is the sum of all the frequencies. Multiply each number by its frequency, add those all up, and then divide by n. n = 2+5+8+12+12+0+1 = 40 Σxƒ(x)=1(2)+2(5)+3(8)+4(12)+5(12)+6(0)+ 7(1) = 151 x̄ = 151/40 = 3.775 Answer from Away-Reading on reddit.com

How do I find the mean?
You can find the mean, or average, of a data set in two simple steps: · Find the sum of the values by adding them all up. · Divide the sum by the number of values in the data set. · This method is the same whether you are dealing with sample or population data or positive or negative numbers.

What are the different types of means?
The arithmetic mean is the most commonly used mean. It’s often simply called the mean or the average. But there are some other types of means you can calculate depending on your research purposes: · Weighted mean: some values contribute more to the mean than others. · Geometric mean: values are multiplied rather than summed up. · Harmonic mean: reciprocals of values are used instead of the values themselves.

What’s the best measure of central tendency to use?
The mean is the most frequently used measure of central tendency because it uses all values in the data set to give you an average. · For data from skewed distributions, the median is better than the mean because it isn’t influenced by extremely large values. · The mode is the only measure you can use for nominal or categorical data that can’t be ordered.

Mean, Median, Mode, Range Calculator
In general, mean, median, mode and range should ideally all be computed and analyzed for a given sample or data set since they elucidate different aspects of the given data, and if considered alone, can lead to misrepresentations of the data, as will be demonstrated in the following sections. The statistical concept of the median is a value that divides a data sample, population, or probability distribution into two halves. Finding the median essentially involves finding the value in a data sample that has a physical location between the rest of the numbers.

Final Answer: To find the mean of a data set, add all the numbers together and then divide by the total count of those numbers. This gives you the average value of the data set. For example, the mean of the numbers 4, 8, 6, 5, and 3 is 5.2.
; Explanation: To find the mean of a data set, follow these steps:
Add all the numbers together. This total is called the sum.
Count the total number of values in the data set. This is how many numbers you have.
Divide the sum by the number of values. The result is the mean or average of the data set.
Example:
Consider the data set: 4, 8, 6, 5, 3.
First, calculate the sum: 4 + 8 + 6 + 5 + 3 = 26
Next, count the number of values: There are 5 numbers in this set.
Finally, divide the sum by the number of values to find the mean: 5 26 = 5.2
So, the mean of this data set is 5.2.
; Examples & Evidence: For example, for the data set 10, 20, and 30, you would add those numbers to get 60, then divide by 3 (the count of numbers), resulting in a mean of 20.
The mean is commonly defined in statistics as the sum of all values divided by the count of those values, which is a fundamental calculation used in data analysis.

Final Answer: To find the mean of a data set, you need to add all the values together, then divide the sum by the number of terms in the set. ; Explanation: For example say the set is:
1 2 3 4 5
Add all the values together:
1 + 2 + 3 + 4 + 5 = 15
Now divide by the number of terms (each separate number). There are 5 terms:
5 15 = 3
3 is the mean of the set. ;
