Addition Rule of Probability

It simply refers to the likelihood of an event taking place whenever the occurrence of an event is uncertain. The probability of a single event can be calculated by dividing the number of successful trials of that event by the total number of trials.

Expected Value

When a large number of trials are performed for any random variable ‘X’, the predicted result is most likely the mean of all the outcomes for the random variable and it is known as expected value also known as expectation. The expected value, also known …

Probability Distributions

Understanding probability is necessary to know the probability distributions. In statistics, probability is how the uncertainty of an event is measured. This event can be anything. The most common examples include tossing a coin, rolling a die, or choosi…

Basic Probability

The simple definition of probability it is a chance of the occurrence of an event. It is defined in numerical form and the probability value is between 0 to 1. The probability value 0 indicates that there is no chance of that event occurring and the prob…

Textbook Question

Chapter 4, Problem 1EA

Although experiments typically manipulate some aspect of the environment to create different treatment conditions, it is also possible to manipulate characteristics of the participants. For example, researchers can give some participants a feeling of success and others a feeling of failure by giving false feedback about their performance or by rigging a task to make it easy or impossible (Thompson, Webber, &c Montgomery, 2002). By manipulating the participants’ experiences, it is possible to examine how people’s performance and attitudes are influenced by success and failure.

Other research has manipulated the participants’ mood. Showing movies, playing music, or having participants read a series of positive (or negative) statements can induce different mood states (positive, negative, neutral). Being able to manipulate mood in the laboratory allows researchers to study how mood influences behaviors such as memory (Teasdale Be Fogarty, 1979) or the ability to read emotions in facial expression (Bouhuys, Bloem, &c Groothuis, 1995), and how other factors, such as alcohol consumption, affect mood (Van Tilburgh & Vingerhoets, 2002).

Suppose you are planning a research study in which you intend to manipulate the participants’ mood; that is, you plan to create a group of happy people and a group of sad people. For example, one group will spend the first 10 minutes of the experiment listening to upbeat, happy music, and the other group will listen to funeral dirges.

(L0 2) Do you consider the manipula- tion of people’s moods to be an ethical

(LO 2) Would you tell your participants about the mood manipulation as part of the informed consent process before they begin the study? Explain why or why not.

(LO 2) Assuming that you decided to use deception and not tell your participants that their moods are being manipulated, how would you justify this procedure to an IRB? What could you do to minimize the negative effects of manipulating people’s moods (especially the negative mood group)?
