What is suicide prevention? Why are schools reluctant to implement suicide prevention programs particularly if there has not been a suicide or suicide attempt made within the student body? Do you agree or disagree with their concerns? Explain.

Discuss the concept of degrees of freedom in the context of t-tests and their significance for making accurate statistical inferences. How do degrees of freedom differ between z-tests and t-tests?
In recent news, there has been debate about the effects of screen time on children’s cognitive development. Choose a specific cognitive outcome measure (e.g., attention, memory, executive function) and write a research question for a one-sample t-test study to investigate whether the average score of a group on that measure differs significantly from a well-established normative population means. Be sure to specify the:
Dependent variable
Relevant population (Sample)
Predetermined value (which can be hypothetical)
Complete the following readings from your textbook, Essentials of Statistics for the Behavioral Sciences:
Chapter 8: Introduction to Hypothesis Testing
Chapter 9: Introduction to the t Statistic
ANSWER
Degrees of freedom in t-tests and their significance for making accurate statistical inferences
In statistical hypothesis testing, degrees of freedom (df) represent the number of independent values that can vary in the calculation of a statistic. In the context of t-tests, degrees of freedom are crucial for determining the t-distribution and making accurate statistical inferences about the population mean.
The degrees of freedom for a t-test depend on the sample size (n) and whether the population variance (σ²) is known or estimated. When the population variance is known, the degrees of freedom are simply n-1. However, in most cases, the population variance is unknown, and the sample variance (s²) is used as an estimate. In this case, the degrees of freedom for a t-test are n-2.
The degrees of freedom directly influence the shape of the t-distribution, which is used to determine the p-value and assess statistical significance. As the degrees of freedom increase, the t-distribution approaches the standard normal distribution, making it more likely to observe extreme t-values.
In summary, degrees of freedom are essential for understanding the behavior of the t-distribution and making accurate statistical inferences about the population mean. They reflect the variability in the data and determine the p-value associated with a particular t-statistic.
Research question for a one-sample t-test study on screen time and attention
In recent years, concerns have been raised about the potential negative effects of screen time on children’s cognitive development, particularly attention. To investigate whether screen time is associated with attention deficits, a one-sample t-test study could be conducted.
The research question for this study would be:
“Does the average attention score of a group of children with high screen time differ significantly from the well-established normative population mean for attention?”
Specifics of the study
Dependent variable: Attention score
Relevant population (sample): Children with high screen time
Predetermined value: The well-established normative population mean for attention
By comparing the average attention score of the sample group to the established normative mean, the study aims to determine whether there is a statistically significant difference between the two groups. A significant difference would suggest that high screen time is associated with attention deficits.

Prejudice has traditionally been assumed to be the product of some form of malice, brought about by social or emotional forces. In recent years, there has been increasing research on how prejudice can result from cognitive processes, without malicious intent. Discuss how and why cognitive processes can produce prejudice. What is the impact of culture on prejudice? Once stereotypes and prejudices are formed, how do they come to be self-perpetuating?

Adolescence is a period of life in which one is subjected to concerns surrounding self-esteem and impression management. Utilizing the following categories, select four to provide personal examples of how your personal views and style of expression were shaped by others (parents, peers, teachers, community, etc.).
impression management
social tuning
social comparisons
mindsets
intrinsic/extrinsic motivation
causal theories

Provide a personal example of how your personal views were shaped by others for each of the four categories selected.
Provide a personal example of how your style of expression (physically, verbally, and in writing) were shaped by others for each of the four categories selected.

Contrast rule-based and rule-free decision making and learning. Provide real life examples of each type of learning/decision making.

Several scenarios that depict ethical dilemmas in psychological research are provided in the assignment instructions. Select the one scenario most relevant to your personal and/or professional interests to begin this assignment. Briefly, you will compose a professional letter to your graduate research advisor discussing the hypothetical situation (scenario), why it is an ethical dilemma, and present two ways of handling the situation (courses of action) given your interpretation of principles that are most at odds. You should present these two courses of action in equally compelling manners, following the assignment instructions. You will then respond to two of your peer’s letters as if you were the advisor giving a recommendation.
