Information about the Information and how you get the information
Ranges
100
When the median is greater than the mean and more of the data is on the right (usually on a dot plot).
What is Skewed Left?
100
The entire amount of objects for the survey, even if it only uses a sample.
What is the Population?
100
The number that is repeated the most in a series of data. It is used to find things in common, things that are popular, or get an idea of what is happening in the data.
What is the Mode?
100
The information you use to find measures of center. It is key to finding the Population, Census, Sample, Parameter, and Statistic. It is also used as the information of your survey or graph.
What is Data?
100
The difference between the minimum and maximum of your data. You can find this by subtracting the maximum by the minimum.
What is the Range?
200
When the mean is greater than the median and there is more data to the left (usually data is on a dot plot).
What is Skewed Right?
200
The survey of the entire population (when the entire population is your group).
What is a Census?
200
When you line up all of your data up in numerical order and find the exact center. If there are two numbers in the center, you add them together and divide by two.
What is the Median?
200
What you use to find the Parameter and Statistic. It is conducted to find the mean, median, and mode.
What is a Survey?
200
Where the data lies on the graph. Usually from the minimum amount to the maximum amount.
What is the Spread?
300

The type of plot used to show the Minimum, Quartile 1, the Median, Quartile 3, and the Maximum. The two dots on the end (Minimum and Maximum) connect to the box (box ranges from Q1 to Q3 and has a line (median) which splits it). *Hint: 4 words

What is a Box and Whisker Plot?

300
The result of the Census. It is found when taking a survey of the entire population.
What is Parameter?
300
When you add all of the numbers in a set of data and then divide by the amount of numbers there are, you get this (sometimes called an average).
What is the Mean?
300
It's not picked from a certain criteria. In order to insure that it is fair and not based on generic patterns in the data, this is used.
What is a Random Sample?
300
When you subtract Q1 from Q3 and find the difference. This is your ______.
What is the Interquartile Range (IQR)?
400

A plot that uses a number line at the bottom of it, then marks the data by stacking it up on a certain number. *Hint: 2 words

What is a Dot Plot?

400
A section of the population that you will use to conduct a survey. It could be random or have criterion to fit into your ______.
What is a Sample?
400

Subtracting each piece of data by the mean and then find its absolute value is the first step. Then, you add all of the absolute values together. This is known as your _____.

What is Mean Absolute Deviation (MAD)?

400
Used to assign numbers in a fair way (for a random survey), it is simply indiscriminate numbers jotted down. The numbers are put into rows (called lines) and then split into any number (based on the maximum amount of digits in your survey).
What is a Random Number Table?
400
DAILY DOUBLE!!!!!! Mr. Smith's class is going to the Zoo. He needs to give each kid a number so that when they return from the zoo, they will do a project on the animal that the number represents. However, Mr. Smith is having problems deciding on how to give students arbitrary numbers. What should he use to assign random digits to the students?
A Random Number Table
500
When the mean and median are almost or exactly the same and the data is almost perfectly centered.
What is Symmetrical?
500
The result when a survey is taken on a sample. It could be taken by measures of center.
What is a Statistic?
500

It refers to the amount that the data points differ from each other. There are four commonly used measures of it: range, variance, standard deviation, interquartile range.

What is Variability?

500
DAILY DOUBLE!!!!!!!!!! Mr. Bobby has to find out how many kids like pizza in his class. He decides to pick kids that have freckles only. He conducts the survey with the sample but then calls it a parameter. What is wrong?
It is a statistic because it comes from a sample of the class.
500

A plot that distributes data (usually by 10). It shows the frequency of data points. The digit with a greater place value is the base and the numbers that fall into that row are put next to it. *Hint: 4 words
