Example Question #11 : How To Find Mode
Find the mode of the set of numbers:
Step 1: We must define the mode of a set. The mode of a set is defined as a number in a given set that you see the most often when compared to other numbers in the set.
Step 2: Let's go through the data and see what numbers we have:
We see that in the given set, we have the numbers .
Step 3: Count how many times each number appears and record down the results:
appears five times
appears seven times.
appears three times.
appears two times.
all appear 1 time each.
Step 4: Compare the number of times each number repeats and choose the highest number, which is the mode.
The highest number is , which means that the mode of the set of number is .
Example Question #111 : Statistics
Ms. Shannon gives her class a math test. The following represent their scores:
100, 100, 90, 98, 97, 96, 96, 86, 84, 96, 87, 70, 100, 96
What is the mode of the class's scores?
The mode of a set of numbers is the number that occurs most often.
100, 100, 90, 98, 97, 96, 96, 86, 84, 96, 87, 70, 100, 96
The above sets when put in ascending order is,
70, 84, 86, 87, 90, 96, 96, 96, 96, 97, 98, 100, 100, 100
100 occurs 3 times
96 occurs 4 times
and all other values occur only once.
In this case, the score that occurs most often is 96.
Example Question #143 : Data Analysis
Find the Mean and Mode of the data set.
The mean is the average of the data
The mode is the data point that appears the most often. In this case the mode is because it appears twice.
Example Question #112 : Statistics
A set of 6 numbers is listed below.
is an even integer that is greater than 10 but less than 21. If is added to the set of numbers, all of the following could be the mode except:
The mode is the value that occurs most in a set of numbers.
Because n is a whole, even number that is greater than 10 and less than 21, it must be either 12, 14, 16, 18 or 20. Because n cannot be 22, 22 cannot be the mode.
Example Question #144 : Data Analysis
Alice rolled a single -sided die times and recorded the top number of the die after each roll. Her results were:
.
What is the mode of this collection of data?
The "mode" is defined as thevalue which occurs most often in a collection of data. To determine which number came up most often during Alice's rolls of a single die, count how many times the numbers through appeared in the data set:
came up times.
came up times.
came up times.
came up times.
came up times.
came up times.
Since the number was rolled most often, is the mode of this set of recorded throws of the die.
Example Question #112 : Statistics
Determine the mode of the Dot Plot.
To determine the mode, we need to count how many diamonds are on each number. The mode is the most frequently occurring number.
Since has a frequency of , it is the mode.
Example Question #113 : Statistics
Week 1 Homework Time Week 2 Homework Time
The above tables show how much time Amanda spent doing homework during the first 2 weeks of school. Which week has the largest standard deviation?
The first step is to calculate the mean for each table.
Recall how to find the standard deviation
Now we will apply this to each table.
Since , is our answer
Example Question #114 : Statistics
There are ten numbers in a set. The numbers are 6, 4, 10, 12, 2, 6, 4, 5, 3, and 4. Find the mode.
The mode is the number that appears most frequently in a set. It is the most common number. The number 4 appears three times in the set and more than any other number. Therefore, it is the mode.
