Quiz Answer Key and Fun Facts

Answer:
**25**

First, we need to find the sum of the five data points, which is 5 x 20 = 100. Then, we subtract 5, 15 and 30 from 100, which gives us 100 - 5 - 15 - 30 = 50. This 50 is the sum of the two unknown data points. We are given that the two unknown data points share the same value. So, 50 / 2 = 25, which is the answer we are looking for.

Answer:
**Multiplication and exponentiation**

Let say we have three data points, which are 1, 3 and 9. The arithmetic mean is (1 + 3 + 9)/3 = 4.333. On the other hand, its geometric mean is (1 x 3 x 9)^(1/3) = 3.

Answer:
**Root mean square**

Trigonometric functions give both positive values (above the x-axis) and negative values (below the x-axis). RMS (root mean square) gives a positive value which indicates the magnitude (distance) of a varying quantity.

Answer:
**Both 1 and 2.**

When there are two numbers that occur with the same highest frequency, both of them are the modes of that set of data.

When there are two numbers that occur with the same highest frequency, both of them are the modes of that set of data.

Answer:
**Peak**

The Gaussian distribution is also known as the normal distribution. Since the mode is the data that occurs most frequently, therefore we can find the value at the peak of the graph.

The Gaussian distribution is also known as the normal distribution. Since the mode is the data that occurs most frequently, therefore we can find the value at the peak of the graph.

Answer:
**There is no mode.**

This is the problem when we use the mode as the measure of central tendency. In this case, there is no mode, since each data point occurs only once.

Answer:
**35**

There are 6 observations in the set of data. So, if we try to find the middle value, it is the value between 30 and 40. To find the median, we find the arithmetic mean for 30 and 40, which is (30 + 40)/2 = 35.

Answer:
**Arrange the data points in ascending or descending order.**

We need to arrange the data points in either ascending or descending order. Then, we find the position of the middle value and we trace down that number.

Answer:
**All of these.**

As the name suggests, percentile divides the data points into 100 equal parts. Decile divides them into ten and quartile divides them into 4.

Answer:
**Mean = mode = median**

For a positively-skewed graph (skewed to the right), the mean is less than the median, which is less than the mode. On the other hand, for a negatively-skewed graph (skewed to the left), the mode is less than the median, which is less than the mean.

For a positively-skewed graph (skewed to the right), the mean is less than the median, which is less than the mode. On the other hand, for a negatively-skewed graph (skewed to the left), the mode is less than the median, which is less than the mean.
