Tom's Math Page!! Hi I'm Tom and this is my Extension Maths page. I am a Year 8 and this is my second year in extension maths.

 * Outliers are numbers away from the group.
 * Clusters are large groups of numbers that are simialer.
 * Trends are patterns in a group of numbers.
 * Multivariate data is when the number has more than one varable.
 * Varables are when something is not consistent.
 * Samples are data or a group of numbers that can be used for testing.
 * Surveying is when you test a group of things with a list of or tests.
 * Patterns in data is when data has a trend.
 * Relationships in data is when data or numbers is linked somehow to more data or numbers.
 * Tally charts are a type of graphs that counts whole number discrete data.
 * Frequency table shows the frequency in data/numbers.
 * Pictographs are a type of graph that is good at displaying discrete data useing pictures.
 * Bar graphs are a type of graphs that u displays discrete data useing bars.
 * Histograms are a type of bar graph used for displaying continuous data.
 * Strip graph is usaully used for displaying discrete data useing a bar that has different colours and shapes on it.
 * Pie graphs show discrete data useing a circular graph.
 * Dot plots are a type of graph that can shw discrete and continuous data usein a line of dots to show the values.
 * Stem and leaf graphs is a graph that shows that the stem is in the middle and the numbers are coming off the side.
 * Scatter plots shows discrete and continuous data useing dots in specific places on the graph.
 * Box and whisker graphs are used for displaying discrete useing a box and a line to display values.
 * Line graphs are good at displaying continuous data useing a line that displays time/quantity and many more.
 * The median is the number in the middle of the data.
 * To get the mean you must add up all the numbers in data then divide by how many number there are.
 * The mode is the most common number.
 * The range is the difference between the highest and the lowest number.
 * The interquartile range is the difference between the 1st quarter and 3rd quarter.
 * Implications are when you make imformation better.
 * Conclusions are the results from a test or survey.
 * Generalisations is when you genralize about data.

This includes a bar, line, pie and scatter plot graphs on it. I Hope you like it.
