data is data that is true and measures what it claims it is going to measure (Reineke
(n.d.) . Valid data can be broken down into two parts: internal and external.
Internal data is the way data is collected and or the purpose of the data. The
second is external data. This is data that covers all grounds; all aspects

c) Explain when data
would be invalid and provide an example or two. ?
would be invalid if there are not enough numbers, or the way the design of the
test does not measure what it’s supposed to. Data can also be invalid if it only
measures certain ages, certain ethnicities, or certain places (Reineke (n.d.).

data is data that produces the same results. There are different types of
assessments that produce reliable data: administering the same test twice that
produces similar results, administering different tests with the same type of
questions that produce the same results, or test items alone that have the same
types of questions produce similar results. The essential key is that no matter
how assessments are given, results are always the same (Reliability &

can be unreliable if it is incomplete or inconsistent.
Data can be unreliable if it is incomplete. If data is incomplete then it
would be deemed false. Data can also be unreliable if it is not consistent
meaning different subjects that are not put together but are actually the same
thing (Reliability & Validity (n.d.).
a) What is test bias? ?
Test bias is when a test can be deemed unfair. It can be deemed unfair
for various reasons, such as the format of the test. It can cater to only
certain minority groups who will score high, while other groups will score low.
Items can also function differently for different cultural backgrounds. Some
may have learned the content some may have not. In short, a test can be biased
based on content, structure, or groupings: test items do not connect/relate to
a certain topic (Price, Warne, Yoon, 2014).

explored that discuss bias in tests. ?

c) List at least three types of bias and provide a brief
definition for each type. ?
Construct bias- A test that measures
what is supposed to measure.
Content bias- A test that caters to a specific ethnic group more than it does
Predictive bias- A test that does not predict all ethnic group outcomes
Types of Assessments ?
Provide your explanation of the following types
of assessments. Two or three sentences on each would be adequate, but to
receive credit for your response you must also provide a specific example.
. a) Performance-based assessment- a broad test based on a
particular unit or standard that requires critical thinking. An example is a
portfolio that demonstrates all learning and compiles all assignments in a
course of study. ?
. b) Ability test- A test that measure strengths & weakness of a person. An
example of an ability test is a IQ test. ?
. c) Aptitude test- An intelligence test that measures through verbal communication
and numbers. An example test would be a numerical test that covers stats,
graphs, and figures.
. d) Personality test- A test that measures people’s personality and
c) IQ test- measures a person’s
intelligence, processing skills
. d) Criterion-referenced test – measures students skills on a
specific standard (ex: CCSS standard. An example is a teacher or collaborative
learning team generated test.
. e) Norm-referenced test- measure students as a whole of the national
average scores. An example would be a high stakes test.
. f) Formative assessment – An assessment used to check for understanding
after something has been taught (a specific standard, objective, goal)
. g) Summative assessment – An
assessment given after multiple lessons or units have been taught or at the end
of the year ?
V.Quantitative & Qualitative Data
a) What is the
difference between quantitative and qualitative data? ?
The difference between Quantitative and Qualitative data is Qualitative
measures data without numbers, through questioning and how things are
naturally, Quantitative measures data with numbers (Saul, 2017).

data for a research project in your major / program of study. ?

receiving high achievement?
d) Formulate and
provide examples of two questions that would be used to collect qualitative
data for a research project in your major / program of study. ?

approaches are being done to ensure every student has the opportunity to

a) What is an empirical
An Empirical study is research that is done through observation or
experience to solve a question or experiment (Sociological Research (n.d.).
b) How is a
meta-analysis different from an empirical study? ?
meta analysis reviews a study while empirical study is the study itself. Meta
analysis breaks down the study (Haidich, 2010).

paragraph explaining how the use of empirical studies is required for this

Descriptive Statistics and Inferential Statistics

Descriptive statistics describes what we are looking at in data making it

b) Write a brief paragraph to explain the difference between
Descriptive Statistics and Inferential statistics. ?
The difference between descriptive and inferential statistics is how data
is used. Descriptive data describes the data being analyzed, providing
important details and descriptions but conclusions and predictions are not met.
Inferential data takes it a step further in providing more rigorous
calculations and making inferences to further the study (Diffrence Between
