Basic Questions Quiz On Mean, Median, Mode And Range!

1) What is the median?

Average of the data

Middle score of the data

Spread of the data

Most common score

The median is the middle score of the data. It is the value that separates the higher half from the lower half of the data set when it is arranged in ascending or descending order. Unlike the average, which is affected by extreme values, the median provides a more representative measure of the central tendency of the data. It is especially useful when dealing with skewed distributions or outliers.

Explanation

The median is the middle score of the data. It is the value that separates the higher half from the lower half of the data set when it is arranged in ascending or descending order. Unlike the average, which is affected by extreme values, the median provides a more representative measure of the central tendency of the data. It is especially useful when dealing with skewed distributions or outliers.

2) What is the mean?

Average of the data

Middle score of the data

Spread of the data

Most common score

The mean is a statistical measure that represents the average of a set of data. It is calculated by summing up all the values in the data set and dividing it by the total number of values. The mean provides a measure of central tendency and is commonly used to describe the typical or average value in a data set. It is different from the median, which represents the middle score, and the mode, which represents the most common score.

It is different from the median, which represents the middle score, and the mode, which represents the most common score.

3) How do you find the median?

Add up all the individual scores and divide by the total number of scores

Subtract the lowest score from the highest score

Arrange the scores in order and determine which lies in the middle

Add the lowest and highest scores together

To find the median, you need to arrange the scores in order from lowest to highest. Then, you determine which score lies in the middle. The median is the value that separates the higher half from the lower half of the scores. It is not found by adding or subtracting the scores, but by organizing them and identifying the middle value.

To find the median, you need to arrange the scores in order from lowest to highest. Then, you determine which score lies in the middle. The median is the value that separates the higher half from the lower half of the scores. It is not found by adding or subtracting the scores, but by organizing them and identifying the middle value.

4) 3, 4, 6, 7, 2, 5, 4, 8, 4, 5 What is the mode for this set of scores?

0

4

3

5

The mode is the value that appears most frequently in a set of scores. In this set of scores, the number 4 appears three times, which is more than any other number. Therefore, the mode for this set of scores is 4.

Explanation

The mode is the value that appears most frequently in a set of scores. In this set of scores, the number 4 appears three times, which is more than any other number. Therefore, the mode for this set of scores is 4.

5) 7, 6, 8, 4, 3, 9, 10, 1, 0, 11, 13 What is the median?

9

7

Cannot tell

6

To find the median of a set of numbers, you arrange the numbers in ascending order and then find the middle value.

Given the set: 7, 6, 8, 4, 3, 9, 10, 1, 0, 11, 13

Arranging them in ascending order: 0, 1, 3, 4, 6, 7, 8, 9, 10, 11, 13

There are 11 numbers in total, so the median is the middle number, which is the 6th number in this case.

Therefore, the median is 7.

To find the median of a set of numbers, you arrange the numbers in ascending order and then find the middle value.

Given the set: 7, 6, 8, 4, 3, 9, 10, 1, 0, 11, 13

Arranging them in ascending order: 0, 1, 3, 4, 6, 7, 8, 9, 10, 11, 13

There are 11 numbers in total, so the median is the middle number, which is the 6th number in this case.

Therefore, the median is 7.

6) 4, 7, 3, 8, 9, 15, 11, 10, 4, 4, 6

What is the range of these scores?

18

15

12

3

The range of a set of numbers is the difference between the largest and smallest numbers in the set. In this case, the largest number is 15 and the smallest number is 3. Therefore, the range is 15 - 3 = 12.

Explanation

The range of a set of numbers is the difference between the largest and smallest numbers in the set. In this case, the largest number is 15 and the smallest number is 3. Therefore, the range is 15 - 3 = 12.

7) On a graph of rainfall vs. years which set of values lie on the x-axis and which lie on the y-axis?

X-axis: yeary-axis: rainfall

X-axis: numbersy-axis: values

X-axis: rainfally-axis: years

X-axis: valuesy-axis: numbers

The x-axis represents the independent variable, which in this case is the year. The y-axis represents the dependent variable, which is the rainfall. The year is being measured and plotted along the x-axis, while the amount of rainfall is being measured and plotted along the y-axis.

Explanation

The x-axis represents the independent variable, which in this case is the year. The y-axis represents the dependent variable, which is the rainfall. The year is being measured and plotted along the x-axis, while the amount of rainfall is being measured and plotted along the y-axis.

8) What scores do you need to add to this data to make the median 7? 0, 3, 7, 6, 5, 9, 5, 8, 4, 10

5, 12, 10

25, 33, 1

11, 12, 13

0, 6, 2

To find the median of a set of numbers, we arrange them in ascending order and then find the middle value. In this case, the given data is already in ascending order, so the median is the average of the two middle values, which are 6 and 7. To make the median 7, we need to add numbers that are greater than 7. The numbers 11, 12, and 13 are greater than 7, so adding them to the data will increase the median to 7.

9) What score do you need to add to this data to make the mean 7? 0, 3, 7, 6, 5, 9, 5, 8, 4, 10

7

14

No value can be added

20

add all the score together = 57
(57 + x)/11 = 7
57 + x = 77
x = 77-57
x = 20

Explanation

add all the score together = 57
(57 + x)/11 = 7
57 + x = 77
x = 77-57
x = 20

10) 7, 6, 8, 4, 3, 9, 10, 1, 0, 11, 13 What is the mean?

5.5

6

6.55

13

The mean (or average) is found by adding all the numbers together to get their total sum, and then dividing that sum by the total number of values.

For the numbers 7, 6, 8, 4, 3, 9, 10, 1, 0, 11, and 13:

First, add all the numbers: 7 + 6 + 8 + 4 + 3 + 9 + 10 + 1 + 0 + 11 + 13 = 72

Next, count how many numbers there are, which is 11.

Finally, divide the total sum (72) by the number of values (11): 72 ÷ 11 = 6.55 (approximately).

So, the mean of these numbers is about 6.55.
