“One hurdle is a talent and skills gap. The United
States alone, McKinsey projects, will need 140,000 to
190,000 more people with “deep analytical” skills,
typically experts in statistical methods and data-analysis
technologies. McKinsey says the nation will also need
1.5 million more data-literate managers, whether
retrained or hired.”

Introduction to
Research Design
What is a hypothesis?
The term “hypothesis” describes
an untested theory.
The researcher anticipates a relationship
between a theory and the real world.
To be an acceptable hypothesis, the theory
must be testable; the researcher must be
able to make observations through testing to
{ falsify, fail to falsify} the hypothesis.
A failure to falsify is
not equivalent to proving your
hypothesis is true
Explain the difference between
hypothesis and research design?
Answer: While hypothesis furnishes the theory for
the study, research design determines the study’s
structure and its process to test the hypothesis.
Research design forces the researcher to think
about and prevent possible problems before
they occur.
I.	 The research design specifies the method used to gather data to
test the hypothesis.
II.	Research design specifies where and when the data is collected.
III.	How will the data be standardized?
IV. The data is tested in multiple ways for greater information.
V.	What standards will the researcher use to accept or reject the
hypothesis?
Every study makes assumptions.
Name some.
Why must the lawyer be aware of
the study’s assumptions?
Assume a study uses historic records to
compare its college students’ SAT scores.
The study claims the data establishes that
its students who have higher SAT scores
gravitate toward one area of study vs
another area of study.
The use of SAT scores inherently includes an
unstated assumption that SAT scores accurately report
the intelligence capacities of the students.
Also, using these historic documents assumes equal
testing procedures and assumes accurate recording
in the historic document of those SAT testing results.
REMEMBER:
In a sense, a lawyer and a scientist are not that different.
A good place to challenge the researcher’s
study start with the assumptions.
The study’s validity will fall if the assumptions lack validity.
This can be a source for a legal (and a scientific) challenge.
