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.

PSY 520 Week 8 Discussion 1
To determine whether a new sleeping pill has an effect that varies with dosage, a researcher randomly assigns adult insomniacs, in equal numbers, to receive either 4 or 8 grams of the sleeping pill. The amount of sleeping time is measured for each subject during an 8-hour period after the administration of the dosage. What type of design is this, and what type of statistic is needed to analyze the data?
PSY 520 Week 8 Discussion 2
Dr. Bill Board designs a 2 X 2 between-subjects factorial design, where Factor A is word frequency (low or high) and Factor B is category cues (no queues or cues). Assume that the data are intervals. What type of statistic is needed to analyze the data?

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
“LuckyUnlucky” 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.
I have flipped an unbiased coin three times and got heads, it is more likely to get tails the next time I flip it.
The Rovers play Mustangs. The Rovers can win, lose, or draw, so the probability that they win is 13.
I roll two dice and add the results. The probability of getting a total of 6 is 112 because there are 12 different possibilities and 6 is one of them.
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.
I flip two coins. The probability of getting heads and tails is 13 because I can get Heads and Heads, Heads and Tails, or Tails and Tails.
13 is an unlucky number so you are less likely to win raffles with ticket number 13 than with a different dumber.
