Degree: Sum of the exponents on the variables in a term
Line of best fit: A straight line that comes closest to the points on a scatter plot
Outlier: A point that differs significantly from the rest of the data
Inference: A conclusion based on reasoning and data
Scatter Plot: A graph that shows the relationship between two sets of data
Independent Variable: A variable for which values are freely chosen and do not depend on the values of other variables. Displayed on the x-axis.
Dependent Variable: A variable whose value depends on the value of another variable. Displayed on the y-axis.
Positive Correlation: Data increasing up to the right
Negative Correlation: Data decreasing down to the right
No Correlation: Data has no trend
Correlation: The observed pattern between the independent and dependent variables
Perimeter: The distance around the outside of a shape
Area: The amount of space covered on the inside of a 2-D figure
Composite Figures: Figures made up of a number of basic shapes
Area of Composite Figure: Area of all the combined shapes that make up the figure
Perimeter of Composite Figure: The distance around all of combined shapes

Hello, my name is Sohyun Kim, and I am in grade 9. This site is for my math summative project, so no hateful comments please. I generally like to read, draw, read manga, and watch anime in my spare time.

definitions.
Polynomials: Algebraic expressions made up of terms
Monomial: 1 term
Binomial: 2 terms
Trinomial: 3 terms
Terms: Made up of a coefficient and variable(s)
Power: Product of identical factors and consists of 2 parts- exponent and base. Coefficient: ----
Variable: ----
Constant/constant term: A term with no variable
Hypothesis: A theory or statement that is either true or false
Statistics: The collection, organization, and analysis of numerical data
Primary Data: Data that comes from experiments and surveys done by researchers
Secondary Data: Data that already exists- comes from sources such as the internet, magazines, and Statistics Canada
Interpolation: Prediction involving a point within the set of data
Extrapolation: Prediction involving a point outside the set of data
Linear Relation: Relation between 2 variables, forms a straight line
Non-Linear Relation: Relation between 2 variables, does NOT form a straight line
Curve of best fit: Curve that comes closest to the points of a non-linear relation
First Differences: -----
Slope: The steepness of a line- ratio of the rise to the run between both points
Direct Variation: A relationship between 2 variables in which one variable is a constant multiple of the other
Partial Variation: When a relationship between 2 variables have both a fixed and variable amount
