Power: Product of identical factors and consists of 2 parts- exponent and base. The three types of scatterplots are the following kinds: positive correlation scatterplot (follows a positive linear function), negative association scatterplot (follows a negative. Terms: Made up of a coefficient and variable(s) Polynomials: Algebraic expressions made up of terms I go on Statistics Canada and search up how many deaths were reported in Canada in 2005. Learn to create scatter plots, analyze scatter plots for correlation, and use scatter plots to make predictions. I go around to all the grade 9 classrooms asking for their favourite colour out of the two- red or blue. 1 The scatter plot that I have seems very likely to have a non-linear relationship. The process is as follows:Ĥ) Organize data (spreadsheet, table of values)Ħ) Analyze data (look for trends/relationships)ħ) Conclusion- state if your hypothesis was true or notīasically, all this means is you make a hypothesis, perform an experiment, get all the data, and come to a conclusion with the data you have.ĮXAMPLE: Drivers' age VS risk of car accidentĪs the drivers' age increases, the risk of car accidents increases.Īs the drivers' age increases, the risk of car accidents do not increase.Īs the hours studying decreases, the final grade will decrease.Īs the hours studying decreases, the final grade will not decrease.ĮXAMPLES OF: Primary Data & Secondary Data Also, you will learn about the line/curve of best fit, linear/non-linear relationships, different trends in data, first differences, distance-time graphs, and the scientific process.įirst, let's look at the scientific process. In this unit, you will mostly learn about scatter plots.
