Quantitative
, as opposed to qualitative investigations provide large amounts of information about a wide range of variables. Quantitative investigations yield numerous results – they are all about the quantity, or large number of results, whereas qualitative are more about the quality.
Which kind of investigations are meant to provide large amounts of information about a wide range of variables quizlet?
Comparative investigations
provide large amounts of information and use a wide range of variables.
What kind of investigations allow for the control of variables?
Answer Expert Verified
An experimental investigation
allows you to control the variables. Explanation: Experimental investigations include a method in which a “fair test” is created and variables are actively planned, managed, and measured in an attempt to gather testimony to confirm or negate a causal relationship.
What are the 3 types of investigations?
There are three types of scientific investigations:
descriptive, comparative and experimental
.
What is 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.
Which kind of investigations are meant to provide large amounts?
Comparative investigations
provide large amounts of information and use a wide range of variables.
Which is a limitation of comparative investigations quizlet?
Which is a limitation of comparative investigations?
They give results that are usually not repeatable by other scientists.
They might show variable relationships that are not actually cause and effect.
How do you manipulate independent variables?
Again, to manipulate an independent variable means
to change its level systematically
so that different groups of participants are exposed to different levels of that variable, or the same group of participants is exposed to different levels at different times.
What are three types of variables in a controlled experiment?
An experiment usually has three kinds of variables:
independent, dependent, and controlled
.
How do you control variables in an experiment?
Variables may be
controlled directly by holding them constant throughout a study
(e.g., by controlling the room temperature in an experiment), or they may be controlled indirectly through methods like randomization or statistical control (e.g., to account for participant characteristics like age in statistical tests).
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 type of investigations are there?
Scientists use three types of investigations to research and develop explanations for events in the nature:
descriptive investigation, comparative investigation, and experimental investigation
.
What is an example of investigation?
An example of investigate is when you run a background check on someone to find out what kind of person he is. An example of investigate is
when the police try to solve a crime
. … Investigate a crime; investigate ways to use less energy; investigate whether the virus is contagious.
What are the steps of a comparative investigation?
- Observations.
- Scientific Question.
- Hypothesis.
- Procedure.
- Variables: Independent and Dependent.
- Data, Graphs, Analysis.
- Conclusion.
What are the benefits of comparative investigation?
Explanation: Benefit of comparative investigation is that
we can get descrete information about specific breed or species
. It is important for the study of behaviour of many organisms. The working and behaviour of various natural aspects can be found.
What are the 2 types of scientific investigations?
The two types of scientific investigation include
fieldwork
, which is the process of collecting evidence outside the laboratory to determine how variables work in a natural setting, and experiments, which involve doing scientific procedures under controlled conditions inside a laboratory.
