A ** sample ** is a piece of data that is used as a practice.
 * cluster **is a group of data in one area. A cluster would usually be found in dot plots.
 * outlier ** is data that is away from the rest of the data.
 * trend ** is a group of statistics that are the same. These are most commonly found in bar graphs.
 * Multivariate data ** is data that has more than one variables.
 * Variables ** are data that is same topic but different surveying item.
 * Surveying ** is when you are recording your data.
 * Patterns ** in data is where you can find groups of data that are in a pattern.
 * relationship ** in data is when there is a some "connection" between to pieces of data.
 * tally chart ** keeps a tally of how many things you are doing statistics on.
 * frequency ** table shows the frequency of the data.
 * pictograph ** is a graph used in pictures instead of bars.
 * bar graph ** is a graph is where the data is shown in bars. thre are four types of bar graphs, column graph, double bar graph, vertical bar graph and hystogram.
 * histogram ** is the only bar graph thats is joined at every bit of data.
 * strip graph ** is a graph that is a strip that is used for dividing data.
 * pie graph ** is a circle where it is seperated into data for each specific thing. You would use a pie graph when doing data on eye colour.
 * dot plot ** is a graph that uses dots for a specific thing eg. progress in class. Dot plots usually have clusters.
 * stem and leaf graphs ** have a stem and numbers come off the stem.
 * scatterplot ** is data that is placed on a graph using co-ordinates.
 * box and whisker graph ** is used to find out the upper and lower quartiles.
 * line graph ** or time series graph is most likely to be used for time measurement. A line graph would be used in data about height and weight.
 * mean ** is all the numbers added up and then divided by the amount of numbers in the series.
 * median ** is the middle number, when all the numbers are put in numerical order.
 * mode ** is the value that is surveyed the most.
 * range **is when the numbers are put in numerical order and the difference between the lowest and highest numbers.
