Statistics Exam Study Guide| Complete
Solution 2024/2025 Guide | Rated A+
Like terms
- Correct Answer - Terms that have the same variable(s) with
the same exponent(s). These terms can be 'combined' using
addition or subtraction.
Multiplication principle of equality
- Correct Answer - "If both sides of an equation are multiplied by
the same number, the result is an equivalent equation."
Ordered pairs
- Correct Answer - "Two numbers written in the form (x, y),
where x represent the x-value or x-coordinate, and y represents
the y-value or y-coordinate."
Origin
,- Correct Answer - "The point (0,0) on a coordinate plane, which
is where the x-axis and y-axis intersect."
Slope-intercept form
- Correct Answer - "A common format that a linear equation can
take that is helpful for graphing purposes. It is of the form y = mx
+ b, where m is the slope of the line and b is the y-intercept."
Slope
- Correct Answer - The value that describes the direction and
steepness of a line drawn on the coordinate plane. It is measured
by 'rise over run.' Rise/Run = (the change in y value)/ (the change
in x value) = (y2 - y1)/(x2 -x1)
Subtraction principle of equality
- Correct Answer - "The fact that we can subtract the same
number to both sides of an equation, and the result will be an
equivalent equation"
Term
,- Correct Answer - "An individual number, a variable, or
numbers and variables multiplied together. They are separated by
addition, +, or subtraction, -, in an expression."
The principle of equality
- Correct Answer - "If you perform equivalent operations to both
side of an equation, the result will always be an equivalent
equation."
The substitution method
- Correct Answer - When a variable is replaced by its known
value in an algebraic expression or equation.
Unlike terms
- Correct Answer - Terms that do not have the same variable(s)
with the same exponent(s). These terms can not be combined
using addition or subtraction.
Value - Correct Answer - A number or numerical worth.
, Variable - Correct Answer - A symbol that represents a
mathematical value.
X-axis - Correct Answer - The horizontal line that passes
through the origin on a coordinate plane.
Y-axis - Correct Answer - The vertical line that passes through
the origin on a coordinate plane.
Y-intercept - Correct Answer - The y-value of the point at which
a line intersects with the y-axis.
Valid data - Correct Answer - Data that results from a test that
accurately measures what it was intended to measure.
Histogram - Correct Answer - A graph that displays data through
vertical bars that show the counts or numbers in each range.
Skewed right - Correct Answer - A skewed distribution where
the long tail of the curve is on the positive side of the peak.
