Chance+and+data_Will


 * Learning Goals**

My learning goals for chance and data are:

__1)__ To learn the difference between mean, median and mode __2)__ To learn how to create frequency tables 3) To actually learn what a frequency table is

To achieve my learning goals, I must learn: How to do said things

To acquire that knowledge, I will use: My teacher, textbook, the internet and my friends

To determine whether I have achieved that goals, I will: Be able to show people how to do it

To demonstrate that I have achieved my goals, I will: Provide evidence

__1)__ The difference between mean, median and mode Mean, median and mode are all different types of averages. Mean is the most common and is sometimes referred to as just 'average'. To find the mean average of something you add all the numbers together and then divide that number by the amount of numbers you added. To find the median average of something you must first order the numbers in ascending order, you then find the one in the middle. If it is an even number you need to find the number in the middle of the two center most numbers. To find the mode average of something you need to order the numbers in ascending order again( you don'e actually have to do this but it makes it a lot easier). You then find the number that occurs the most times.

__2)__ How to create frequency tables



3) What a frequency table is A frequency table is used to measure(surprisingly) how frequent things are. They are normally used to record results of simple surveys. The left column is the different answers for the question asked, the middle is a tally of results and the right is the results. There is a box in which the total number of people surveyed goes.
