Across
- 2. A letter (like x or y) used to represent an unknown or changing number in an equation.
- 5. One of two numbers whose product is 1. You find it by "flipping" a fraction upside down
- 7. The number that is multiplied by a variable in an algebraic expression.
- 9. One of the four regions formed on a coordinate plane by the intersection of the x-axis and y-axis.
- 11. OF CENTER A single number used to describe the "middle" or "typical" value of a data set. Examples include the mean and median.
- 12. A comparison of two quantities by division.
- 14. A stray data value that is much higher or much lower than the rest of the numbers in the set.
- 15. An unfolded, flat 2D pattern that can be folded up to make a 3D solid shape.
- 16. A measure of center found by adding up all the data points and dividing by the total number of points; also called the average.
Down
- 1. To break a complex geometric shape down into simpler shapes, like triangles and rectangles, to find its total area.
- 3. VALUE The distance a number is from zero on a number line, always written as a positive value.
- 4. A special bar graph that shows data grouped into equal intervals rather than individual numbers.
- 6. The exact middle number in a data set when the numbers are listed in order from least to greatest.
- 8. RANGE A measure of variability (spread) that tells you the distance between the first and third quartiles.
- 10. The small, raised number that tells you how many times to multiply a base number by itself.
- 13. A closed, flat 2D shape formed by three or more straight line segments. (No curves allowed!)
