Example Question #361 : Statistics And Probability

Determine the mode of the set.

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

Possible Answers:

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

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

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

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

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

Correct answer:

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

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

Example Question #378 : Statistics And Probability

What is the mode?

13, 12, 14, 15, 15, 16, 16, 17, 18, 15, 14, 13

Possible Answers:

13, 14, 15

14, 15

13, 14

Correct answer:

Explanation:

Mode is the data point that occurs most frequently. If we arrange in increasing order, we have

12, 13, 13, 14, 14, 15, 15, 15, 16, 16, 17, 18 .

occurs most frequently as it appears three times.

Some of them occur twice which isn't good enough.

is the correct answer.

Example Question #56 : Basic Statistics

What is the mode?

7, 6, 5, 2, 8, 7, 6, 4, 9, 10, 1

Possible Answers:

7, 6

Correct answer:

7, 6

Explanation:

Mode is the data point that occurs most frequently.

Let's arrange in increasing order. We have

1, 2, 4, 5, 6, 6, 7, 7, 8, 9, 10 .

and occur twice and are the most frequent. We can have more than one mode so the answer is 6,7 .

Example Question #380 : Statistics And Probability

What is the mode?

17, 5, 18, 9, 9, 17, 18, 5, 17

Possible Answers:

9, 18

17, 18

5, 17

Correct answer:

Explanation:

Mode is the data point that occurs most frequently.

Let's arrange in increasing order. We have

5, 5, 9, 9, 17, 17, 17, 18, 18 .

occurs three times while the rest only twice.

Therefore, is the answer.

Example Question #381 : Statistics And Probability

What is the mode?

-1, -3, 0, -3, 0, -1, 4, 9, 2

Possible Answers:

0, -1, -3

-1, -3

0, -3

0, -1

Correct answer:

0, -1, -3

Explanation:

Mode is the data point that occurs most frequently.

Let's arrange in increasing order. We have

-3, -3, -1, -1, 0, 0, 2, 4, 9 .

-3, -1, 0 occur twice while the rest only once.

Therefore, -3, -1, 0 is our final answer.

Example Question #63 : Basic Statistics

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

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

Possible Answers:

$\small 4$ and $\small 11$

$\small 4$

$\small 5$

$\small 22$

$\small 4$ and $\small 5$

Correct answer:

$\small 4$ and $\small 5$

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.

Let's go one number at a time. The number four appears four times; the number two appears two times; the number five appears four times.

Thus, the numbers $\small 4$ and $\small 5$ both appear the most amount of times, four times each! We have two modes!

Example Question #391 : Statistics And Probability

John's past five test scores were

85, 90, 81, 85, 94 .

What is the mode of his test scores?

Possible Answers:

Correct answer:

Explanation:

The mode of a set of numbers is the number that occurs the most times.

Since 85 appears twice, and all other numbers appeared only once, 85 is the mode.

${\color{Red} 85}, 90, 81, {\color{Red} 85}, 94$

Example Question #403 : Statistics And Probability

Consider the following set of numbers:

25, 27, 36, 32, 41, 22, 28, 33, 44, 51, 37, 32

Find the mode of the set.

Possible Answers:

Correct answer:

Explanation:

The mode of the set is the most repeated number in the set.

First organize the set in order from smallest to largest.

22, 25, 27, 28, 32, 32, 33, 36,37, 41,44, 51

From here we can see more clearly when there is a repeated number.

$22, 25, 27, 28, {\color{Red} 32, 32,} 33, 36,37, 41,44, 51$

In this case that number is because all other number only occur once.

Example Question #402 : Statistics And Probability

Consider the following set of numbers:

61, 65, 68, 71, 72, 72, 72, 74, 79, 82, 86, 88, 88

Find the mode of the set.

Possible Answers:

Correct answer:

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.

Example Question #403 : Statistics And Probability

Consider the following set:

15,17,12,13,14,11,14,10,22,16,9

Find the mode of the set.

Possible Answers:

Correct answer:

Explanation:

The mode of the set is the number that occurs the most times in the set.

$15,17,12,13,{\color{Red}14},11,{\color{Red} 14},10,22,16,9$

In this case that number is since all other numbers are only seen once in the data set.
