Mean, Median, Mode and Range

Definitions: Mean - When people say "average" they usually are talking about the mean. You can figure out the mean by adding up all the numbers in the data and then dividing by the number of numbers. For example, if you have 12 numbers, you add them up and divide by 12. This would give you the mean of the data. 

Median - The median is the middle number of the data set. It is exactly like it sounds. To figure out the median you put all the numbers in order (highest to lowest or lowest to highest) and then pick the middle number. If there is an odd number of data points, then you will have just one middle number. If there is an even number of data points, then you need to pick the two middle numbers, add them together, and divide by two. That number will be your median. 

Mode - The mode is the number that appears the most. There are a few tricks to remember about mode: If there are two numbers that appear most often (and the same number of times) then the data has two modes. This is called bimodal. If there are more than 2 then the data would be called multimodal. If all the numbers appear the same number of times, then the data set has no modes. They all start with the letter M, so it can be hard to remember which is which sometimes. Here are some tricks to help you remember: Mean - Mean is the average. It's also the meanest because it take the most math to figure it out. Median - Median is the middle. They both have a "d" in them. Mode - Mode is the most. They both start with "mo". 

Range - Range is the difference between the lowest number and the highest number. Take, for example, math test scores. Let's say your best score all year was a 100 and your worst was a 75. Then the rest of the scores don't matter for range. The range is 100-75=25. The range is 25.

Pacific Ring of Fire

Background Knowledge:
In class, we are studying the earth's layers and plate movement.  The Ring of Fire is a horseshoe pattern of volcanic activity on the earth's surface.  It is the movement of the Pacific plate that causes volcanic activity, because as the plate moves underneath the over-riding plates, it melts.  The hot melted crust then becomes less dense and rises up through the cold crust to create volcanoes.  Because the Ring of Fire is a plate BOUNDARY, plates are moving past each other here, and so earthquakes are also created.

Task:
You are in charge of researching at least 5 different countries that are connected to the RING of FIRE.  You can find stories of natural disasters in those countries, and discover what the citizens did to recover from the disasters.
