Example Questions
Example Question #101 : Statistics And Probability
Find the mean of the following set of numbers:
The mean is the average, which is the sum of all the numbers divided by the number of values.
Example Question #102 : Statistics And Probability
Which answer shows the mean, median, mode, and range of the data set.
Mean = Numbers added together divided by how many numbers there are.
Median = Middle number when put in order from least to greatest.
Mode = Most occurring number.
Range = Highest minus lowest number.
Added together the data set equals 130. There are 13 numbers.
Mean = 10
Middle number when least to greatest is 
Median = 
Most occurring number is 
Mode =
Highest - Lowest number equals: 
Range =
Example Question #103 : Statistics And Probability
Jill is an all-star forward in hockey. She is the leading goal scorer on her team. She scored 
The mean is the average of all the numbers combined.
To get the answer you would add the goals in each game together then divide by the total number of games.
So,
Example Question #104 : Statistics And Probability
Jill is an all-star forward in hockey. She is the leading goal scorer on her team. She scored 
The mean of an equation is also referred to as the average. So to solve this question all you need to do is add the total number of goals together and divide it by the number of games.
So,
Example Question #105 : Statistics And Probability
Refer to the following set of numbers:
What is the mean of the set?
In order to find the mean of the set, we find its average. Do this by adding up all of the numbers in the set, then dividing that answer by the amount of numbers in the set.
Example Question #106 : Statistics And Probability
Refer to the following set of numbers:
Find the mean of the set.
In order to find the mean of the set, we find its average. Do this by adding up all of the numbers in the set, then dividing that answer by the amount of numbers in the set.
Example Question #107 : Statistics And Probability
Refer to the following set of numbers:
Find the mean of the set.
In order to find the mean of the set, we find its average. Do this by adding up all of the numbers in the set, then dividing that answer by the amount of numbers in the set.
Example Question #107 : Statistics And Probability
Find the mean of the following data set:
In order to find the mean for any data set, one must find the sum of all the values in the data set and then divide this sum by the number of values. Adding all of our values:
We then take this value and divide by 
Hence, our mean is 
Example Question #108 : Statistics And Probability
Sarah has 
In order to find the mean of a set of numbers, we need to follow two steps:
Step 1 - First, we need to find the sum of all of the numbers in the set. For this problem, that means we need to add together the number of coins in each of the 
So, there are 
Step 2 - Next, we need to divide the sum that we got in Step 1 by the total amount of numbers in the set. We added together 
So, the mean is 
Example Question #109 : Statistics And Probability
A sample of 
The mean is simply the average of the five scores, which we find by adding the scores together and dividing by the number of students:
