· An outlier is when a piece of data stands out from the rest. · A cluster is when a group of data are close together. · A trend is when a group of data has a pattern. · Multivariate data is when data has more than one variable. · A variable is when something is not consistent. · Surveying is when someone asks questions about a certain topic to other people. · A pattern in data is when groups of data make up a pattern. · A relationship in data is when a group of data is connected in some way. · A tally chart is used to count discrete data. · A frequency table shows the frequency of data. · A pictograph is a type of graph using pictures instead of bars, lines etc. · A histogram is a type of bar graph that is used for continuous data. · A strip graph is a type of graph that is a strip which divides data. · A pie graph is a circular graph that is used to measure percentages. · A dot plot is a type of graph that uses dots to measure specific data. · A stem and leaf graph is a type of graph that has a “stem” in the middle and numbers coming off the side. · A box and whisker graph is a type of graph that finds the lowest, lower quartile, middle, upper quartile and highest number. · The mean is when all the numbers are added up and divided by the amount of numbers you added together. · The median is the middle number when all numbers are put in order from smallest to largest. · The mode is when you have two or more numbers of the same value. · An implication is a recommendation for someone. · A conclusion is the end result. · A generalization is a general sum up. · A sample is data/group/number that can be used for something

· A scatter plot is a type of graph that only uses numerical data.

· A bar graph is a graph that shows data in bars. There are four types of bar graphs and they are a histogram, a column graph, vertical graph and a double bar graph.This one is a double bar graph.

· A line graph or time series data are types of graphs that measures continuous data.
