I have also not taken a statistics class since high school so I am looking forward to reintroducing myself to these materials.

I got the same answers as everyone else but will post them anyway. I haven’t taken a statistics class before so calculating variance and standard deviation were new to me but turned out to be much easier than I thought they would be.

]]>1. Nope. Just a paragraph or two. Kind of like an expanded abstract. The letters are just there for guidance.

2. Example (though I can’t format it properly here):

Johnson, D. W., Johnson, R., & Dudley, B. (1992). Effects of peer mediation training on elementary school students. Mediation Quarterly, 10, 89-99.

This study is concerned with students’ development of a shared understanding of the procedures needed to constructively manage interpersonal conflicts at an elementary school. The purpose of the study is to determine the frequency and nature of student-student conflicts and the strategies they use to manage them as well as determine the impact of a negotiation and mediation training program on the frequency, nature, and strategies. To measure this, students filled out forms about conflicts they were involved with, teachers kept logs of when students used mediation procedures outside the classroom, students wrote responses to hypothetical conflicts, student response to role-played conflicts on videotape. This was four different measures, two of which relied on fictional conflicts, which might or might not be transferable to real-world conflicts. The other two measures involved students self-reporting, which could be inaccurately written by elementary aged students, and teachers keeping a daily log but of casual observations, which could result in inaccuracies. The sample was divided into two groups randomly and only included children described as “middle-class”. The independent variable was the training program; One group got it and the other didn’t. Descriptive statistics used compare types of conflicts as a percentage of all conflicts, types of strategies used by trained and untrained students in both the written and role-played conflict simulations as a percentage of all strategies, and the percentage of trained and untrained students who used the steps in the negotiation process defined by the training. I don’t see inferential statistics here. The sample size is only 25 or 30 students in each group, and the real question is how the training affected or didn’t affect these particular students. The results show that negotiation and mediation can be taught to elementary aged children, but there is no reason to say that the specific results of this study can be generalized to the larger population.

3. It’s mostly so you can identify if it’s a quantitative article and what statistic the authors used.

No worries. It’s the first time out of the box. We’ll talk about it on Monday night.

I don’r remember having taken a stats class so the the last two are new to me. Also all the 3,745 new terms are all swirling around in my head :/

My math skills have improved being in a math class the last few years at my school. I took notes on the entire article and the lesson for Module 2. It was a big day of stats for me. It’s a lot of new vocabulary and terms to try to wrap my head around. I didn’t really get a good idea of variance and standard deviation so I googled it and found this that helped. To calculate the variance follow these steps:

1.Work out the Mean (the simple average of the numbers)

2.Then for each number: subtract the Mean and square the result (the squared difference).

3.Then work out the average of those squared differences.

I was then able to get the standard deviation, but I had to play around with it for a few minutes. Whew… I think I need to play guitar for a few minutes before my next homework task tonight.
