Polynomials
| Term | Definition |
|---|---|
| Polynomial | An expression where every variable has a whole number exponent |
| Monomial | A polynomial with one term |
| Binomial | A polynomial with two terms |
| Trinomial | A polynomial with three terms |
| Simplify | To combine like terms by way of addition or subtraction or reduce fractional expressions where applicable |
| Like Terms | Two or more terms that are either constants or contain the same variable part or same variables and powers |
| Constant | Any real number |
| Descending Order | When terms are written from greatest to least degree |
| Degree of Polynomial | The greatest degree of its terms |
| FOIL | First, Outer, Inner, Last - method of multiplying two binomials |
| Factoring | The process of rewriting an expression or polynomial as an equivalent product of two or more factors |
| Greatest Common Factor (GCF) | The greatest factor all terms share in common |
| Quadratic Expression | Polynomials of the form ax^2+bx+c, where a, b, and c are coefficients, and a is non-zero |
| Perfect Square Trinomial | A quadratic expression that is the product of a binomial, either (a+b) or (a−b), squared |
| Difference of Squares | A quadratic expression of the form a^2−b^2 that can be factored as (a+b)(a−b) |
| Range | The difference between the minimum and maximum value of a data set. |
| Outlier | A data value that is less than 1.5 times the interquartile range below the first quartile or is greater than 1.5 times the interquartile range above the third quartile. |
| Center | The mean or median of a data set. |
| Spread | The range, the standard deviation, or the interquartile range of a data set. |
| Two-way frequency table | A visual display of the counts of frequencies for two categorical variables. |
| Joint frequency | Entries found in the interior cells (non-total column and row) in a two-way frequency table, which are the counts of data where both variables occur. |
| Marginal frequency | The total of the cells in a row or column for a category of a two-way frequency table. |
| Categorical data | In statistics, categorical data, or qualitative data, can take on one of a limited, and usually fixed, number of possible values, which are assigned to groups based on their properties. |
