Objective Assessment #1
Given the following set of numbers: 3.3, -2.3, -16, 25. What are the square roots of the whole
number?
A. +/- 2.3
B. +/- 3.3
C. +/- 4
D. +/- 5 Correct answer-D. +/- 5
Composite Number Correct answer-A number with more factors that just one and itself.
Equivalent Fractions Correct answer-Different fractions that represent the same value.
X-Axis Correct answer-The horizontal line that passes through the origin on a coordinate plane.
Qualitative Data Correct answer-Non-numeric information based on some quality or characteristic.
No Correlation Correct answer-There is no apparent overall trend between the two variables. If the
correlation coefficient is 0, this only rules out a linear trend. There could be a non-linear or
curvilinear trend.
Extrapolate Correct answer-Using information from a data set to make predictions about data
outside of the original set.
Event Correct answer-An outcome, or set of outcomes, whose chance of occurrence can be
represented with a probability.
Given the following set of numbers: 10, 2.5, -4, -4.5, 5. What is the sum when adding together only
the whole numbers?
A. 5.5
B. 11
C. 12.5
D. 15 Correct answer-D. 15
Operation Correct answer-In Mathematics, an operation is a procedure which generates a new
value from one or more operands, or Mathematical values.
Conditional Proportion Correct answer-A proportion where one part of the proportion is a
variable, or unknown quantity.
Coefficients Correct answer-A number by which a number is multiplied. This number is written in
front of the variable(s).
Mean Correct answer-Average, calculated by adding a series of elements in a data set together and
dividing by the total number in the series.
Outlier Correct answer-An observation point that is statistically distant from the other observations
in the dataset.
, Regression Line Correct answer-The line of best fit to show the relationship between variables, the
one that minimizes distance from each data point to the line.
Experiment Correct answer-A procedure that can be done repeatedly which has a well defined set
of outcomes.
Given the following expression: 4 + 7 × (6 - 3)2. What is the answer using proper order of operations?
A. 25
B. 46
C. 67
D. 99 Correct answer-C. 67
Multi-Step Expression Correct answer-An expression or equation with more than two values and
two or more operators that requires multiple steps to be solved.
Improper Fraction Correct answer-A fraction where the number in the numerator is more than the
number in the denominator.
Y-Intercept Correct answer-The y-value of the point at which a line intersects with the y-axis.
Check Sheet Correct answer-A structured form or table that allows data to be collected by marking
how often an event has occurred in an certain interval.
Linear Correct answer-An expression or equation of degree 1.
Least Squares Correct answer-A technique for finding the regression line.
Sample Size Correct answer-The number of different outcomes for an experiment.
Given the following expression: 5 x (30 - 27)2 + 4. What is the correct answer using the proper order
of operations?
A. 34
B. 49
C. 65
D. 81 Correct answer-B. 49
Exponents Correct answer-Sometimes called a power, it is a quantity that represents repeated
multiplication.
Least Common Multiple (LCM) Correct answer-The smallest number in value that is a multiple of
two or more numbers.
Order of Operations Correct answer-A set of rules that defines the order in which Mathematical
operations should be performed.
Numerical Summary Correct answer-A number used to describe a specific characteristic about a
data set.
Joint Frequencies Correct answer-The frequency counts in each cell of the table.
