Example Questions
Example Question #1 :Range
Which is the greater quantity?
(A) The midrange of the data set
(B) The midrange of the data set
(A) and (B) are equal
(B) is greater
It is impossible to determine which is greater from the information given
(A) is greater
(A) is greater
The midrange of a data set is the mean of its least and greatest elements. The midrange of the first data set is; that of the second data set is. (A) is greater.
Example Question #41 :Data Analysis And Probability
Setis defined as:
Setis made by doubling the values in set.
What is the range of values in set?
找到一组数字的范围,你不even have to put them in order. You merely need to subtract the smallest value from the largest. Given the way of constructing setby doubling set's values, the largest and smallest values inwill directly correlate to the same in set:
Smallest:
Largest:
Therefore, the range is:
Example Question #1 :How To Find Range
The members of setare defined as the values for:
For values ofbetweenand.
What is the range of set?
找到一组数字的范围,你不even have to put them in order. You merely need to subtract the smallest value from the largest. Given the way that we construct setfrom the function,我们只是需要使用这个函数来找到smallest and largest values. Luckily, that is pretty easy for this question. The smallest will beand the largest will be
Smallest:
Largest:
Therefore, the range is:
Example Question #1 :How To Find Range
Setis defined as:
The members of setare defined by the function:
, whereis a member of set.
So, for instance, set T containsbecause for, we get:
What is the range of set?
We first need to determine the members of set. Using our function, we will get:
Our largest value is, and our smallest value is; therefore, the range is
Example Question #2 :Range
Given the below set of numbers find the range:
Range for a set of data is defined as the difference between the biggest and smallest number.
First we find the biggest number which is 15, we then subtract the smallest number in this set which is negative 2 as shown below:
Remember, when subtracting a negative number we must add the numbers.
Example Question #6 :How To Find Range
Given the below set of numbers, find the range:
In order to find the range, we must subtract the smallest number from the biggest number.
We must convert the fractions to have a common denominator which is 10.
Therefore, the range of this set is
.
Example Question #7 :How To Find Range
Given the below set of numbers, find the range:
In order to find the range, we must subtract the smallest number from the biggest number.
We must convert the fractions to have a common denominator which is 10.
Therefore, the range of this set is
.
Example Question #8 :How To Find Range
Find the range of the data set provided:
In order to answer this question correctly, we need to recall the definition of range:
Range:The range of a data set is the difference between the highest value and the lowest value in the set.
In order to find the range, we need to first organize the data from least to greatest to find the lowest and highest values:
Next, we can solve for the difference between the highest value and the lowest value:
The range for this data set is
Example Question #11 :Data Analysis
Find the range of the data set provided:
In order to answer this question correctly, we need to recall the definition of range:
Range:The range of a data set is the difference between the highest value and the lowest value in the set.
In order to find the range, we need to first organize the data from least to greatest to find the lowest and highest values:
Next, we can solve for the difference between the highest value and the lowest value:
The range for this data set is
Example Question #12 :Data Analysis
Find the range of the data set provided:
In order to answer this question correctly, we need to recall the definition of range:
Range:The range of a data set is the difference between the highest value and the lowest value in the set.
In order to find the range, we need to first organize the data from least to greatest to find the lowest and highest values:
Next, we can solve for the difference between the highest value and the lowest value:
The range for this data set is
