A tally chart is a group of 5 lines put together with 4 going down and 1 going diagonal. A pictograph uses pictures instead of bars. A dot plot is mostly the same as a bar graph except with dots instead of bars. A median is the middle number in a group of data. A mean is the average number of a group of data. A range is the lowest number to the highest number like 12-79. A box and whisker graph is used to find the median the 75% the 25% in a group of numbers with boxes and lines connecting them. An outlier is a number way out of the other numbers. Normally used in box and whisker graphs. A histogram is a bar column graph on it's side and shows continuous data. A cluster is group of data. A scatterplot is a graph that uses dots to show 2 groups of data like the wieght and the length of diferent fish. A trend shows the performanace of data. A conclusion is the overall result of your findings. The mode is the number in a group of data that appears the most. The interquartile range is the two middle quartiles in a group of data. A stem and leaf graph compares two or more variables for a particular item. A variable is item that is being compared. A sample is a set of data. Multivrariate data is data obtained from more than one variable. Surveying is collecting data through a questionnaire. A pattern in data is a repeated trend. Relationships show connections between different sets of data. Frequency tables are those that show a variable being measured on the left of other variables. Time series data is data measured over a period of time. Implications compare data in order to make a conclusion. Generalisations are conclusions from one set of data that are not necessarily correct. A bar graph has bars that show data.The bars can go horizontal or vertical. A pie graph is shaped as a pie.It shows data in sections.

A line graph is a graph that shows continuous data. It is a line connecting up dots.
