Experimental subject design
Question
Read this
paragraph and write a summary. (What you like about it, what you know about it,
or if you agree, etc.)
The discussion topic is the between subject design. An
experimental design is the foundation of numerous experiments. Its functions are
comparable of a scientific blueprint, allowing information and data to be
included. The main goal is to receive most of the questions in our research
answered to create a design for observations. The design used in an experiment
is determined mainly by the nature of the hypothesis. However, prior research,
the kind of information the researcher is seeking, and practical problems in
running the experiment also influence choice of design. Although, there are an
infinite variety of potential hypotheses, most research questions use a few
basic designs. Three aspects of the experiments play the biggest part in
determining the design: (1) the number independent variables, (2) the number of
treatment conditions needed to make a fair test of the experimental hypothesis,
(3) whether the same or different subjects are used in each of the treatment
conditions (p.262). Basically, in my observation designs are an action or event
that creates a function of many things. Recruiting subjects may be the most
crucial part of a research experiment. Creating an atmosphere or location will
determine the outcome of the experiment. At most, researchers utilize numerous
resources to begin an experiment. Different obstacles come in play during
selections, mainly grouping an adequate amount of individuals that are willing
to participate. Making sure that the subjects you choose will allow the
experimenter to come up with data for accurate findings. If individuals in a
population are all like one another on the dependent variable small samples are
adequate. When individuals are likely to be quite different, larger samples are
needed. if we take larger samples, we are more likely to obtain individuals who
represent the full range of behaviors on the dependent variable- some people
who score, some who score low, and some who score in between (p.265).

Solution
Experimental subject design
Subject design is one where the study subjects are
subjected to every condition of the study. From the paragraph, it is evident
that there is an understanding of the subject design of the study’s
experimental design. What I like about the paragraph is the organization of
information from the subject design’s importance, process, and results.
Researchers use different methods of study to answer questions based on their
requirements. I know about the information in the paragraph that subject design
is effective in experimental studies that the condition subjects are exposed to
is not important in the study results. What is tested in the study is the
difference in subjects in exposure to similar environments and not in different
environments. Creating a design effectively guides studies, answers the study
questions, and answers hypotheses.
I conquer that several aspects affect the design to
be used in an experiment, and they include the pretesting and protesting,
variables that may be independent or dependent and the groups which are the
experiment and control groups. I agree that study design approaches and sets of
methods and procedures effectively analyze information and variables to develop
an event or a function of several different things. I know about determinants
of experiment outcome because several factors are interrelated. Several variables
about the subject of study determine the outcome of the experiment. The
experimental study design abides by a certain design and works to answer
hypotheses through variables manipulation, measurement, comparison and
calculation. The study is performed in a controlled and guided environment.
Finally, it is without a doubt that a large sample size quantifies to more
accurate outliers identification and offers a small window for error.
