Why is statistics important in various fields such as education and law enforcement?

• It helps in making informed decisions.

• It is only used in scientific research.

• It is only used for academic purposes.

• It is not relevant to real-world applications.

What is the first step in calculating the median of a data set?

• Add all the numbers together.

• Arrange the numbers in ascending order.

• Divide the total by the number of data points.

• Find the mode of the numbers.

If a data set is 3, 4, 4, 5, 6, 7, 8, what is the median?

• 5

• 6

• 4

• 7

What does the mode represent in a data set?

• The average of all numbers.

• The number that appears most frequently.

• The middle value when numbers are ordered.

• The difference between the highest and lowest values.

How do you calculate the mean of a data set?

• Subtract the smallest number from the largest.

• Add all numbers and divide by the number of data points.

• Find the middle value of the data set.

• Identify the most frequently occurring number.

In a data set of 60, 70, 85, 70, 90, what is the mode?

• 60

• 90

• 70

• 85

What is the mean of the data set: 60, 70, 85, 70, 90?

• 80

• 71

• 75

• 85

If a data set has a mean of 5.25, which of the following values is above the mean?

• 4

• 5

• 5.25

• 6

What is the significance of understanding the mode in a data set?

• It helps identify the most common value.

• It determines the average value.

• It shows the range of the data.

• It is used to calculate the median.
