In summary, the four statistical questions are important in statistics because they help us to systematically analyze and interpret data. The measures of central tendency, such as mean, median, and mode, can help us determine the average of a dataset. Understanding the shape or distribution of data can provide valuable insights into the data. Outliers, or extreme values, can be identified and dealt with using statistical methods, such as interquartile range or z-scores. They can either be removed or given less weight in the analysis.

So. Why don't you tell us what you need help with? We aren't going to do your homework for you.

(29) A "tic-tac-toe board" has 9 positions. There are 9 places to put the first "X", then 8 places to put the next, and then 7 places to put the last: there are total of 9(8)(7)= 504 possible configurations for 3 "X"s on the board. How many of those have all three "X"s in the same vertical column? How many have all three in the same horizontal row? How many diagonal are there?

## 1. What are the four statistical questions that need a detailed answer?

The four statistical questions that need a detailed answer are: What is the mean? What is the median? What is the mode? What is the standard deviation?

## 2. Why is it important to answer these four statistical questions?

Answering these four statistical questions provides a comprehensive understanding of the data set and allows for accurate interpretation and analysis.

## 3. How do you calculate the mean, median, mode, and standard deviation?

The mean is calculated by adding all the values in a data set and dividing by the number of values. The median is the middle value in a data set when arranged in ascending or descending order. The mode is the most frequently occurring value in a data set. The standard deviation is calculated by finding the square root of the variance, which is the average of the squared differences from the mean.

## 4. What do the mean, median, mode, and standard deviation tell us about a data set?

The mean, median, mode, and standard deviation provide different measures of central tendency and variability in a data set. The mean gives the average value, the median gives the middle value, the mode gives the most frequently occurring value, and the standard deviation gives the spread of the data around the mean.

## 5. How can we use the answers to these four statistical questions to make informed decisions?

The answers to these four statistical questions can help us understand the characteristics of a data set and make comparisons between different data sets. This information can be used to make informed decisions in various fields such as business, medicine, and social sciences.
