Objective Assessment | Questions and
Answers Rated A+ | 2025/2026 Guide
Independent Variable - Correct Answer - The variable that may be the
cause of some result, or is presented as the variable that offers an
explanation. Also called an explanatory variable.
Regression Equation - Correct Answer - An equation used to model the
relationship between the response and explanatory variables in a
regression.
Tree Diagram - Correct Answer - A diagram that records all the events in
a sample space by attaching each new set of events to each branch of
the earlier events. The number of outermost branches gives the sample
size.
What is 2/3 + 1/4?
A. 11/12
B. 3/12
C. 3/7
D. 8/3 - Correct Answer - A. 11/12
,Positive Number - Correct Answer - A number whose value is greater
than zero. On the number line, positive numbers are to the right of zero.
Rate - Correct Answer - A ratio that compares two quantities having
different units of measure.
Quadrants - Correct Answer - The four sections of the coordinate plane,
separated and defined by the x-axis and y-axis.
Minimum - Correct Answer - The smallest value in a set.
Non-Linear - Correct Answer - An expression or equation that is
illustrated by something other than a straight line.
Linear Interpolation - Correct Answer - Estimation using the linear
regression equation in between known data points.
Sample Space - Correct Answer - The entire set of outcomes for a trial
or experiment.
A patient's protein intake for today has been 15.76g, 8.49g, and 22.58g.
What is the total protein intake rounded to the nearest tenth of a
decimal?
A. 46.5g
, B. 46.8g
C. 46.9g
D. 47g - Correct Answer - B. 46.8g
Square Root - Correct Answer - A number that produces a specified
number when it is multiplied by itself.
Rounding - Correct Answer - A method of estimating in order to make
working with a number easier.
Term - Correct Answer - In Mathematics, a term is an individual number
or variable, or numbers and variables multiplied together in an
expression. Terms are separated by addition or subtraction signs.
Stem Plot - Correct Answer - A visual representation of data in which
individual points are plotted to the right of a vertical line, or chart, and the
left (the "stem") shows the interval categories.
Scatterplot - Correct Answer - A graph that uses dots on a coordinate
plane to show the relationship between two quantitative variables.
Population - Correct Answer - An entire pool from which a sample is
drawn.
