Topic 1 – Descriptive Statistics Project
Directions:
Use the following information to complete the questions below. While APA format

in students just prior to the midterm exam. The research used an anxiety
self-quiz to gage the student’s anxiety. The score for 30 students are given
here.

a frequency table with class, frequency, relative percent, and cumulative
percent that has 6 classes to describe the distribution of the data in SPSS.
2. Use

There are many misconceptions about probability
which may include the following.
·
All
events are equally likely
·
Later
events may be affected by or compensate for earlier ones
·
When
determining probability from statistical data, sample size is irrelevant
·
Results
of games of skill are unaffected by the nature of the participants
·
“Lucky/Unlucky”
numbers can influence random events
·
In
random event involving selection, results are dependent on number rather than
rations
·
If
events are random then the results of a series of independent events are
equally likely
The following statements are all incorrect. Explain
the statements and the errors fully using the probability rules discussed in
topic two.
1. I
have flipped and unbiased coin three times and got heads, it is more likely to
get tails the next time I flip it.
2. The
Rovers play Mustangs. The Rovers can win, loose, or draw, so the probability
that they win is 1/3.
3. I
roll two dice and ad the results. The probability of getting a total of 6 is
1/12 because there are 12 different possibilities and 6 is one of them.
4. Mr.
Purple has to have a major operation. 90% of the people who have this operation
make a complete recovery. There is a 90% chance that Mr. Purple will make a
complete recovery if he has this operation.
5. I
flip two coins. The probability of getting heads and tails is 1/3 because I can
get Heads and Heads, Heads and Tails, or Tails and Tails.
6. 13
is an unlucky number so you are less likely to win raffles with ticket number
13 than with a different dumber.

A researcher randomly assigns 33 subjects to one of
three groups. Group 1 receives technical dietary information interactively from
an on-line website. Group 2 receives the same information from a nurse
practitioner, while Group 3 receives the information from a video tape made by
the same nurse practitioner.
The researcher looked at three different ratings of
the presentation; difficulty, usefulness, and importance to determine if there
is a difference in the modes of presentation. In particular, the researcher is
interested in whether the interactive website is superior because that is the
most cost-effective way of delivering the information.

Research Question Project
In 1,250-1,500 words, answer the following questions about
possible research options.
Create a research question in the field of psychology that
you are interested in researching. Write questions clearly. Include a brief
background of the problem you are proposing and why it is important to the
field of psychology.
State the null and alternative hypothesis (in both words and
statistical notation) need to address the research question.
Choose which statistical test would be used to conduct the
study and support it with research.
Describe the type of data needs to be collected to conduct
the study and what techniques are best for collecting data.
Use three to five scholarly resources to support your
explanations.

the APA Style Guide, located in the Student Success Center. An abstract is not
required.
This assignment uses a rubric. Please review the rubric
