Example Question #741 : Sat Subject Test In Math I
What is the mode of 8, 7, 5, 4, 12, 13, 7, 2, 7?
The mode is the number that is repeated the most within a set. In our case we see 7 repeated 3 times therefore our mode is 7
Example Question #741 : Sat Subject Test In Math I
What's the mode?
Mode is the number occuring the most in the data set. By rearrangging in increasing order, we see that 
Example Question #3 : Mode
Which value above would be the mode of this particular data set?
The mode is the value that occurs the most times in one set. In the given set that value is 
Example Question #1 : Mode
A class of statistics students scored the following on their last test:
Calculate the mode for this data set.
The mode is the number that shows up more often than the others in a set of data.
If we put our data set in order we see:
98, 65, 85, 100, 76, 50, 88, 63, 70, 65, 70, 99, 82, 80, 78, 65, 94, 66
Becomes,
50, 63, 65, 65, 65, 66, 70, 70, 76, 78, 80, 82, 85, 88, 94, 98, 99, 100.
Therefore, 65 is the mode because it appears 3 times.
Example Question #1 : How To Find Mode
What is the mode of the following data set?
{9, 10, 4, 11, 7, 5, 15, 7, 2, 20, 11, 19, 7, 9}
11
2
9
7 and 9
7
7
Arrange the set in numerical order: {2, 4, 5, 7, 7, 7, 9, 9, 10, 11, 11, 15, 19, 20}.
You can then chart the frequency of each value.
Value (Frequency)
2 (1)
4 (1)
5 (1)
7 (3)
9 (2)
10 (1)
11 (2)
15 (1)
19 (1)
20 (1)
From this you can see the most common value, which is the mode, is 7.
Example Question #744 : Sat Subject Test In Math I
A set comprises ten elements, which are
where 
What can 
The set cannot be bimodal for any value of N.
12 appears in the set most frequently, appearing three times; 19 is second in frequency, appearing twice. 10, 11, 18, and 20 appear once each.
The only number we can set 
Example Question #4 : Mode
Find the mode of the set:
The mode is the most repeated number in the set. To answer this, find the number that occurs the most number of times in the set.
For this problem that gives us the answer of 16 for the mode.
Example Question #14 : Mode
Find the mode of the set:
The mode is the most repeated number in the set. To answer this, find the number that occurs the most number of times in the set.
For this problem that gives us the answer of 22 for the mode.
Example Question #11 : Mode
Find the mode of the set:
The mode is the most repeated number in the set. To answer this, find the number that occurs the most number of times in the set.
For this problem that gives us the answer of 40 for the mode.
Example Question #751 : Sat Subject Test In Math I
Find the mode of the following data set:
Find the mode of the following data set:
The mode is the number which appears most in a number set. In this case, we have a few duplicates, but only one triple:
Therefore, it must be 85, because 85 is the only one which appears more than twice!
