What is the use of median?
It is a statistical measure that helps you understand the sample/population data.
What are the advantages of Range of data?
It is a very easily calculated measure of the spread of data.
What is the third quartle?
The third quartile, often denoted as Q3, is a statistical measure that represents the value below which 75% of the data points in a dataset fall. It effectively divides the highest 25% of the data from the rest, providing insight into the distribution and spread of the data. In a sorted dataset, Q3 can be found by locating the median of the upper half of the data.
HOW are quartiles helpful in describing data?
They are a simple measure of the spread of the data, which is not affected by extreme values.
Can you use the mean to answer a statistical question explain?
You can use the mean to answer some statistical questions: it is a measure of the central tendency of a set of data. However, it is no good in identifying the maximum value of a set of data, for example.
What is the difference between the least square mean and the mean in statistical analysis?
The least square mean is a statistical measure that minimizes the sum of squared differences between data points and the mean, while the mean is the average of all data points. The least square mean takes into account the variability of the data, while the mean does not consider the spread of the data.

What does the IQR tell you about a data set?
It gives a measure of the spread of the data.
What are the advantages of Range of data?
It is a very easily calculated measure of the spread of data.
What measure tells something about the distribution of a data set?
range
What does mean deviation tells us about the data?
It is a measure of how variable the data is. The average distance from the average.
What is meant by the standard deviation of a data set?
It is a measure of the spread of the data around its mean value.

What does Quartile 3 represent?
Quartile 3 (Q3) represents the value below which 75% of the data points in a dataset fall. It is a measure of the upper range of the data, indicating that 25% of the values exceed this point. Q3 is used in statistical analysis to understand the distribution and spread of data, particularly in identifying outliers and the overall shape of the data distribution.
What is standard deviation used for?
Standard deviation is a measure of the spread of data.
What is the usefulness of quartiles in business?
It is a simple but crude measure of the spread of data.
