The class is Psychology - 223 but it's more a Statistics question...

1.I need to describe the hypothesis associated with my research scenario.

2. I need to state my understanding of what each hypotheses mean.

3. I need to identify the null and alternative hypothesis using appropriate statistical symbols and language based on what is being compared in my research scenario.

And can someone please explain to me how to use that immage up load thing that is asking for a URL on the (immage properties), I have no idea what to put in that spot.

PSY 223 Milestone Three Worksheet

Review the critical elements that must be addressed in the final project. Use this worksheet to create Milestone Three. A hypothesis is a position about research outcomes. In this assignment, you will describe two hypotheses associated with your research scenario.

Points to consider: A researcher acts like the coach of a sports team. In a pregame meeting, a coach describes the possible scenarios associated with outcomes of a game. "If we win, it means we go to the playoffs; if we lose it means our season is over." The coach’s specificity helps ensure everyone is clear on what the team is up against and what is at stake. Before doing an analysis, researchers do something similar. They acknowledge potential outcomes of the upcoming analysis. "We can find either: (a) variation in the data reflects chance, or (b) variation in the data is due to a systematic law." Researchers call position (a) null hypothesis (symbolized H0). Researchers call position (b) alternative hypothesis (symbolized Ha). A researcher customizes the hypotheses to a study, using symbols and information about the specific study.

1. Indicate your research hypotheses (null and alternative), incorporating the appropriate symbols. [To answer this question, you need, in part, to look at the research scenario.]

2.State what the hypotheses mean.

[Some overlap may exist with your answer to # 1. These are related rather than mutually exclusive questions.]

Scenario 2 (Forensic Psychology)

Levels of groups' certainties about their eyewitness testimony to a simulated crime were compared. The first group was set up to be "right" in its eyewitness accounts and the second group was set up to be "wrong"; the desire was to see if confidence differed across groups. Thirty-four participants were recruited from a college campus and randomly divided into two groups, both of which were shown a video of a crime scenario (length: 58 seconds) in which the perpetrator's facial characteristics (with respect to the camera) were clearly visible at two separate points and sporadically visible at others. Half the participants then were shown a five-individual lineup that contained the perpetrator in the video ("Group A"), and half the participants were shown a five-individual lineup that did not contain the perpetrator ("Group B"). Participants were asked to (a) identify if and where the perpetrator was in the lineup and (b) provide a rating of confidence on a scale from 1 to 10 (10 being highly confident) that the selection was the same as the person seen in the video committing the crime. All participants signed consent forms, were told they could leave the study at any time, and were told they would be debriefed. Data on the confidence ratings are shown below (also found in the Data Set Scenario 2 Excel file).
