OBJECTIVE ASSESSMENT QUESTIONS AND
ANSWERS
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
D. +/- 5
Composite Number
A number with more factors that just one and itself.
Equivalent Fractions
Different fractions that represent the same value.
X-Axis
The horizontal line that passes through the origin on a coordinate plane.
,Qualitative Data
Non-numeric information based on some quality or characteristic.
No Correlation
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
Using information from a data set to make predictions about data outside of the original
set.
Event
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
D. 15
, Operation
In Mathematics, an operation is a procedure which generates a new value from one or
more operands, or Mathematical values.
Conditional Proportion
A proportion where one part of the proportion is a variable, or unknown quantity.
Coefficients
A number by which a number is multiplied. This number is written in front of the
variable(s).
Mean
Average, calculated by adding a series of elements in a data set together and dividing
by the total number in the series.
Outlier
An observation point that is statistically distant from the other observations in the
dataset.
Regression Line
The line of best fit to show the relationship between variables, the one that minimizes
distance from each data point to the line.
