Measures of central tendency help you find the middle, or the average, of a data set. The 3 most common measures of central tendency are the mean, median and mode. The mode is the most frequent value. The median is the middle number in an ordered data set. This quiz will assess your knowledge of Measures of Central Tendency.

### _________________________ is a type of math that analyzes data.

• A.

Algebra

• B.

Trigonometry

• C.

Statistics

• D.

Averages

C. Statistics
Explanation
Statistics is a branch of mathematics that focuses on the collection, analysis, interpretation, presentation, and organization of data. It involves using various methods and techniques to gather information, summarize data, and make inferences or predictions based on the data. Statistics is widely used in various fields such as business, economics, social sciences, and research to make informed decisions and draw meaningful conclusions from data sets.

### The better way to refer to the bell curve is by calling the same graph a __________________ distribution.

• A.

Normal

• B.

Average

• C.

Curved

• D.

Round

A. Normal
Explanation
The bell curve is commonly referred to as a normal distribution because it represents a symmetrical distribution of data with the majority of values clustered around the mean. The term "normal" in this context refers to the statistical concept of normality, indicating that the distribution follows a specific pattern and is commonly observed in many natural and social phenomena.

### Measures of ____________________________ analyze the center or the middle of a normal distribution.

• A.

Variability

• B.

Means

• C.

Middle

• D.

• E.

Central Tendency

E. Central Tendency
Explanation
Central Tendency measures analyze the center or the middle of a normal distribution. These measures provide information about where the data tends to cluster or concentrate. They include measures such as the mean, median, and mode, which help to summarize and describe the central or typical value of a dataset. By calculating central tendency measures, we can better understand the distribution of data and make inferences about the population from which the data is drawn.

### Which of these are measures of central tendency?

• A.

Mean

• B.

Median

• C.

Mode

• D.

All of the above

• E.

None of the above

D. All of the above
Explanation
The measures of central tendency are statistical measures that represent the center or average value of a dataset. The mean is the sum of all values divided by the total number of values, the median is the middle value when the data is arranged in order, and the mode is the value that appears most frequently in the dataset. Therefore, all of these options (mean, median, and mode) are measures of central tendency.

### ________________ is not a measure of central tendency.

• A.

Range

• B.

Mean

• C.

Median

• D.

Mode

A. Range
Explanation
Range is not a measure of central tendency because it does not provide information about the typical or central value of a data set. Instead, it represents the difference between the maximum and minimum values in the data set. Measures of central tendency, such as the mean, median, and mode, are used to describe the central or typical value of a data set.

### Which of these is the most commonly used measure of central tendency?

• A.

Median

• B.

Mean

• C.

Range

• D.

Mode

B. Mean
Explanation
The mean is the most commonly used measure of central tendency because it takes into account all the values in a data set and provides an average value. It is calculated by summing all the values and dividing by the total number of values. The mean is widely used in various fields, such as statistics, economics, and science, to summarize and analyze data. It provides a balanced representation of the data and is less affected by extreme values compared to other measures like the median or mode.

### Another word for the mean is the _______________________.

• A.

Median

• B.

Mode

• C.

Range

• D.

Total

• E.

Average

E. Average
Explanation
The mean is a statistical measure that represents the average value of a set of numbers. It is calculated by summing all the values in the set and dividing by the total number of values. Therefore, "average" is another word for the mean because it represents the typical or central value of the data set.

### Find the mean of these scores.25, 32, 45, 56

• A.

25

• B.

45

• C.

38.5

• D.

56

C. 38.5
Explanation
The mean is calculated by adding up all the numbers and then dividing the sum by the total number of values. In this case, the sum of the scores is 25 + 32 + 45 + 56 = 158. Since there are four scores, we divide 158 by 4 to get the mean, which is 39.5. However, the given answer is 38.5, which is incorrect.

### The ______________ is the score with the middle value.

• A.

Median

• B.

Range

• C.

Mode

• D.

Average

A. Median
Explanation
The median is the score with the middle value. It is calculated by arranging the scores in ascending order and finding the middle value. Unlike the average, the median is not affected by extreme values, making it a more reliable measure of central tendency. The range is the difference between the highest and lowest values, while the mode is the score that appears most frequently. Therefore, the correct answer is the median.

### When finding the median, you must make sure that ______________ of the numbers are above the median and _________________ of the numbers are below the median.

• A.

2

• B.

4

• C.

Half

• D.

Most

C. Half
Explanation
When finding the median, you must make sure that exactly half of the numbers are above the median and exactly half of the numbers are below the median. This is because the median represents the middle value in a set of numbers, dividing it into two equal halves.

### Find the median of these scores.71, 4, 19, 42, 80

• A.

4

• B.

42

• C.

19

• D.

71

B. 42
Explanation
The median is the middle value in a set of numbers when they are arranged in ascending or descending order. In this case, the numbers are 4, 19, 42, 71, and 80. When arranged in ascending order, the middle value is 42, which is the median.

### Find the median of these scores. 50, 10, 20, 30

• A.

50

• B.

10

• C.

30

• D.

20

• E.

25

E. 25
Explanation
The given set of scores is 50, 10, 20, and 30. To find the median, we arrange the scores in ascending order: 10, 20, 30, 50. There are four scores, so the middle two scores are 20 and 30. The median is the average of these two scores, which is (20 + 30) / 2 = 25.

### The _______________ is the score that occurs most often in a distribution; the scores that appears more than once.

• A.

Range

• B.

Mode

• C.

Average

• D.

Median

B. Mode
Explanation
The mode is the score that occurs most often in a distribution, meaning it is the value that appears more than once. In other words, it is the most frequently occurring score in the dataset. The mode is a measure of central tendency that helps identify the most common value or values in a set of data.
