Bar Graph Whatever helps me get the point across
Circle Graph Ideal for showing percentages (fractions) All the parts add up to a whole
To find the percentage Divide the number in whichever category by the total number. – 10 students are too hot – 12 students are too cold – 2 students arent sure – 1 Teacher thinks it is just right The total is 25
To find the percentage 10/25 = 40% are too hot 12/25 = 48% are too cold 2/25 = 8% arent sure 1/25 = 4% is just right When making the graph: – 1 circle is 360° = 100% – Each percent is 3.6°
Line graph A line graph is useful when a dependent variable changes due to a relationship with an independent variable. The independent variable is x The dependent variable is y
