 You will be learning about mean, median, mode and range... and also learn how to graph...

 

 

 

 

Mean: The sum of the numbers in a set of data divided by the number of pieves of data is the MEAN (average)

To get the mean... you simply add all the numbers in the data set.. then divide the sum of all data by the amount of numbers in the data set, and you get your mean...

Median: The median is the middle number of a set data that is arranged in numerical order. When there are 2 middle numbers, the median will be the mean between the 2 numbers.

To get the median, you simply find the middle number in the data... but it MUST be in numerical order from smallest to largest... if there is an even amount of numbers, you will add the two middle numbers and divide it by 2, giving you the median... that's also getting the MEAN(average) of the two middle numbers.

Mode: The mode is the most common number in a set of data. You can have more than 1 mode. You can have no modes.

To get the mode, you simply just look for a number shown more than once.

Range: The difference between the largest and smallest numbes in a set of data. Range shows how many whole numbers are in between the largest and smallest.

To get the range... you will take the largest number in the data set and subtract it from the smallest number in the data set.

 

 

 

use these sites to help you more on mean, median, mode and range:

Find a set of values to fit these condition

 

Six number with a mean of 7 and a median of 5...

 

 

 

 

In this matter... a graph can be used to organize a set of data given to you.

 

You will usually be given a set of data for you 

 

All graphs must include

    -Title

    -coloured intervals (if bar graph)

    -must be going up by the same amount

       -e.g. 2, 4, 6, 8, 10, 12....

    -labeled x and y axis

 

 Here are the most common graphs that we use:

 

 

A line graph is used to show continuing data; how one thing is affected by another

 

 

 

 

 

 

 A bar graph is used to show relationships between groups or topics.

 

 

Use these sites to help you more on the different types of graphs and information.

Bobby fills a sink with enough water to wash his dog mr. barksalot. He then puts mr. barksalot in the sink and washes him. After he is finished, he takes mr. barksalot out of the sink. then he drains the sink

 

Draw a graph that represents the level of water in the sink from the time Bobby started to fill the sink until the sink was empty. Clearly label your graph.

 

The "y" axis is for the level of water and the "x" axis is for the time. Bobby filled the sink to a third in 2 mins. Put mr. barksalot in the sink water and it went up by another third Gave mr. b a both for 6 mins. then took him out, and drained water empty for 2 mins.
