Across
- 3. line a smooth curve fitted to the set of paired data in regression analysis; for linear regression the curve is a straight line
- 5. coefficient when the regression line is linear (y = ax + b) the regression coefficient is the constant (a) that represents the rate of change of one variable (y) as a function of changes in the other (x); it is the slope of the regression line
- 7. deviation the square root of the variance
- 9. drafting instrument used to draw or measure angles
- 10. interest interest calculated on both the principal and the accrued interest
- 13. the quality of being valid and rigorous
- 14. a variable quantity that cannot be resolved into components
- 15. a straight line or plane that touches a curve or curved surface at a point but does not intersect it at that point
- 16. extending or lying across; in a crosswise direction; at right angles to the long axis
- 17. the people who inhabit a territory or state
- 22. having the character of a polynomial
- 23. circuit a circuit having its parts connected serially
- 24. value the sum of the values of a random variable divided by the number of values
- 25. curve a symmetrical curve representing the normal distribution
- 26. a mathematical notation indicating the number of times a quantity is multiplied by itself
- 27. a straight line from the center to the perimeter of a circle (or from the center to the surface of a sphere)
- 29. a limited period of time
Down
- 1. a straight line segment whose length is magnitude and whose orientation in space is direction
- 2. of or in or along or relating to a line; involving a single dimension
- 3. concerning each of two or more persons or things; especially given or done in return
- 4. a datum that can be represented numerically
- 5. scale a logarithmic scale of 1 to 10 formerly used to express the magnitude of an earthquake on the basis of the size of seismograph oscillations
- 6. distance travelled per unit time
- 8. the source or origin from which something derives (i.e. comes or issues)
- 11. the amount per unit size
- 12. complete change in character or condition
- 17. maintain or assert
- 18. a constant in the equation of a curve that can be varied to yield a family of similar curves
- 19. the quality of being subject to variation
- 20. ratio of the adjacent side to the hypotenuse of a right-angled triangle
- 21. an idea accepted as a demonstrable truth
- 28. ratio of the length of the side opposite the given angle to the length of the hypotenuse of a right-angled triangle
