Example Question #1 : Calculating Mode
Rita keeps track of the number of times she goes to the gym each week for 1260 weeks. She goes 1 day a week for 119 weeks, 2 days a week for 254 weeks, 3 days a week for 376 weeks, and 4 days a week for 511 weeks. What is the mode of the number of days she goes to the gym each week?
119 weeks
1 day/week
511 weeks
4 days/week
2.5 days/week
4 days/week
The mode is the number that comes up most frequently in a set. Rita goes to the gym 4 times a week for 511 weeks. She clearly goes 4 times per week far more often than she goes 1, 2, or 3 times per week. Therefore the mode is 4 days/week. It is NOT 511 weeks. That is the frequency with which 4 days/week occurs, but not the mode.
Example Question #2 : Calculating Mode
For which of the following values of 
None of the other answers are correct.
If the known values are ordered from least to greatest, the set looks like this:
Below are each of the choices, followed by the set that results if it is added to the above set, followed by the median - the middle element - and the mode - the most frequently occurring element.
Only the addition of 11 yields a set with median and mode equal to each other.
Example Question #3 : Mode
Consider the data set 
The set has one mode, 6.
The set has two modes, 6 and 
The set has one mode, 
The set has three modes, 6, 8, and 
The set has two modes, 6 and 8.
The set has one mode, 6.
Of the known elements, 6 occurs the most frequently - three times. Since the unknown 
Example Question #551 : Arithmetic
What is the mode for the following set:
The mode is the number that appears most frequently:
Example Question #5 : Calculating Mode
Determine the mode of the following set of data:
The mode of a set of data is the entry that appears most often within the set. One easy way to determine the mode is by arranging the set in increasing order:
Now that the set is arranged in increasing order, we can see how often each value appears in the set. The value 7 appears three times, which is more than any other entry is repeated, so this is the mode of the set.
Example Question #4 : Calculating Mode
Determine the mode of the following set of data:
The mode of a set of data is the entry that occurs most often within the set. An easy way to determine which entry occurs the most often is by arranging the set in increasing order:
Now we can see that 29 is repeated more often than any other number in the set, so this is the mode.
Example Question #97 : Descriptive Statistics
Determine the mode of the following set of data:
The mode of a set of data is the entry that appears most frequently within the set. An easy way to determine the mode is by arranging the set in increasing order:
Now we can see that the value of 
Example Question #552 : Arithmetic
Determine the mode for the following set of numbers.
The mode is the most frequent number, thus our answer is 
Example Question #553 : Arithmetic
Find the mode of the following set of numbers:
The mode is the most frequent number, thus the answer is 
Example Question #10 : Calculating Mode
Give the mode of the set 
The set has no mode.
The mode of a set, if it exists, is the value that occurs most frequently. The inequality
means that the set
can be rewritten as
The most frequently occurring value is
