What are 3 methods of investigation?
There are three types of scientific investigations:

.
What tasks can be used to start a descriptive investigation?
Descriptive investigations use
careful observations and measurements to develop findings
. Science journals, science logs, and field notebooks are some of the tools scientists use to gather information for descriptive investigations.
What is the correct order in a descriptive investigation?
Ask a testable question
.
Research the topic
.
Collect information via research and observations
.
Make sense of the observation and draw a conclusion
.
What is the goal of a descriptive investigation?
The goal of descriptive investigation is
to describe
. It should provide factual, accurate and systematic descriptions of phenomena without attempting to infer causal relationships. It does not answer questions about the how, when, or why a particular phenomenon occurred.
Why are descriptive investigations repeatable?
Descriptive investigations are
not repeatable because
they are based only on observations made at a single point in time. The results may vary at a different time. In addition, descriptive investigations do not contain variables that may indicate cause-and-effect relationships.
What are the steps of a comparative investigation?
Comparative Investigation:
Involve collecting data on different populations/organisms, under different conditions (ex. Times of year, locations)
, to make a comparison. Example – Using a hand lens to examine the color and texture of four different rocks.
What is an example of an experimental investigation?
Experimental investigations have a control group which does not receive any treatment. For example,
a student might conduct an investigation to answer
the question “What is the effect of light color on plant growth?” In this experiment, the variable color of light is changed by the student.
Which kind of investigations are meant to provide large amounts of information?
Comparative investigations
provide large amounts of information and use a wide range of variables.
What are the six methods of investigation?
They are: methods of
contrastive analysis, operational analysis, distributional analysis, immediate constituents analysis, componential analysis, transformational analysis, method of semantic differentiation
.
What are the techniques of investigation?
For countless years, criminal investigators have relied on six basic investigative techniques to solve crimes; i.e., (1)
the development of informants
, (2) use of undercover agents, (3) laboratory analysis of physical evidence, (4) physical and electronic surveillance, (5) interroga- tion, and (6) where permitted by …

What is descriptive design and its example?
Descriptive research aims to
accurately and systematically describe a population, situation or phenomenon
. It can answer what, where, when and how questions, but not why questions. A descriptive research design can use a wide variety of research methods to investigate one or more variables.
Which statement is a hypothesis?
A hypothesis is a
tentative statement about the relationship between two or more variables
. It is a specific, testable prediction about what you expect to happen in a study.
