  2. 7. Experiment where a sample is divided into groups, where one is manipulated and the other remains unchanged
  3. 13. The Correlation ____ is used to measure how well the data matches a line that would best fit the data
  4. 16. The number that appears most often in data
  5. 18. Study where the researcher purposely attempts to influence the results
  6. 22. An algebraic expression that is the sum or difference of of two or more monomials
  7. 24. Any “rule” that assigns exactly one output value for each input value
  8. 25. Use of a model to predict outputs when the input is within the range of known data

  14. 38. When lines have negative reciprocal slopes
Down
  1. 1. Experiment where a researcher controls the manipulation of the sample through random methods
  2. 3. Use of a model to predict outputs when the input is outside the range of known data

  4. 5. Domains of square root functions are ____ because square roots of negative numbers do not exist
  5. 6. The way the points are situated on the graph
  6. 7. A binomial formed by negating the second term of the binomial
