Basic Math - Mode | Practice Hub

Determine the mode of the set.

$A = \begin{Bmatrix}0, 5, 6, 4, -1, 0, 5, 4, -5, 1\end{Bmatrix}$

$\begin{Bmatrix} 0 , 5 , 4\end{Bmatrix}$

$\begin{Bmatrix} 5 \end{Bmatrix}$

$\begin{Bmatrix} 0 \end{Bmatrix}$

$\begin{Bmatrix} 4 \end{Bmatrix}$

$\begin{Bmatrix} 0 , 5 \end{Bmatrix}$

Explanation

$A = \begin{Bmatrix}0, 5, 6, 4, -1, 0, 5, 4, -5, 1\end{Bmatrix}$

Mode refers to the number occuring most often, so in this example we are looking for the numbers that repeat and how many times they repeat.

repeats twice

Now because all three numbers repeated an equal amount of time, all three then become our mode.

Answer : $\begin{Bmatrix} 0 , 5 , 4\end{Bmatrix}$

What is the mode?

Explanation

Mode is the data point that occurs most frequently.

Let's arrange in increasing order. We have

and occur twice and are the most frequent. We can have more than one mode so the answer is .

What is the mode?

Explanation

Mode is the data point that occurs most frequently.

Let's arrange in increasing order. We have

occur twice while the rest only once.

Therefore, is our final answer.

Consider the following set of numbers:

Find the mode of the set.

Explanation

The mode of the set is the most repeated number in the set. In this case there is number being repeated once and another being repeated twice.

$61, 65, 68, 71, {\color{Red} 72, 72, 72,} 74, 79, 82, 86, {\color{Blue} 88, 88}$

Therefore the answer will be the number that is being repeated twice, .

This number can be seen in red.

What is the mode?

Explanation

Mode is the data point that occurs most frequently.

Let's arrange in increasing order. We have

occurs three times while the rest only twice.

Therefore, is the answer.

Steven is a high school athlete who competes in the long jump. He recorded his last 7 jumps: 15 feet, 18 feet, 19 feet, 12 feet, 15 feet, 18 feet, 15 feet. What is the mode of his long jump lengths?

Explanation

The mode of a data set is the number that occurs most often. Because Steven managed to long jump 15 feet 3 times, 15 feet is the mode.

For a school project, Jonas asked his classmates how many siblings they had. of his classmates had siblings, had sibling, had siblings, and had siblings. What is the mode of the number of siblings his classmates had?

Explanation

In a data set, the mode is the number that occurs most frequently.

Because 18 of his classmates only had 1 sibling, 1 is the number that appears most often.

Find the mode of the following numbers:

Explanation

The mode is the number that occurs the most in a group.

Rearranging our numbers we get:

While does occur twice, occurs three times, and no other number does, so must be the mode.

Anthony takes six math tests and achieves these scores:

Find the mode of these scores.

Explanation

The mode is the number that is repeated most often. In this set of scores, the two numbers repeated are 76 (repeated twice) and 86 (repeated three times). Since 86 is repeated most, it is the mode.

$\small \small \small 11, 23, 32, 1, 4, 4, 4, 2, 2, 4, 3, 5, 5, 5, 5$

Using this set of data, find the mode(s).

$\small 4$ and $\small 5$

$\small 4$ and $\small 11$

$\small 5$

$\small 4$

$\small 22$

Explanation

To find the mode, we must find which number appears the most amount of times. (rememeber: mode = most!)

In this data set:

$\small \small \small \small 11, 23, 32, 1, 4, 4, 4, 2, 2, 4, 3, 5, 5, 5, 5$ ,

the numbers $\small \small \small 11, 23, 32, 3$ and $\small 1$ all only appear once. But the numbers $\small 2, 4,$ and $\small 5$ appear more than once; these are our candidates for the mode.
