Grade 6 PSSA Math Vocabulary 2023

Absolute Value - ANS-the distance the number is from 0 on the number line Additive Inverse - ANS-An expression that can be added to a given expression so that their sum is zero. Algebraic Expression - ANS-A mathematical expression that contains one or more variables. Box-and-Whisker Plot - ANS-A plot that visually represents a set of data. A rectangle (the box) is used to represent the dispersion of points between the first and third quartiles, and line segments (the whiskers) are used to represent the dispersion of points between the minimum value and the first quartile and between the maximum value and the third quartile. A line segment drawn within the box represents the median value. Coefficient - ANS-The constant by which a variable is multiplied. Combination - ANS-A unique set or group of objects, symbols, numbers, etc. Counting Number - ANS-Any number from the set of numbers represented by {1, 2, 3, ...}. (Sometimes referred to as a "natural number." Degree (temperature) - ANS-A unit of measure for temperature. It is represented by the symbol ° and is used in conjunction with the number. Dependent Variable - ANS-The variable in a relation that represents a value determined by the independent variable. Sometimes referred to as the "output variable." Distributive Property - ANS-When a single-term expression is being multiplied by a sum or difference, the single-term expression can be multiplied by each term before finding the sum or difference. That is, a(b + c) = ab + ac or a(b - c) = ab - ac. Expression - ANS-A number or variable, the power of a number or variable, or the sum, difference, product, or quotient of a combination of numbers, variables, and/or powers of a number or variable. Ex. 15xy Greatest Common Factor (GCF) - ANS-The greatest factor that two or more numbers have in common. Histogram - ANS-A type of data display that represents a frequency distribution. The class intervals (buckets) represent numerical data. The class intervals are located on the x-axis and form the bases of contiguous rectangular bars. Frequencies are listed on the y-axis. Independent Variable - Continues...
