Hello,

I have produced a set of statistics for my university assignment using the free statistic calculator found at http://www.statcrunch.com.

I would be grateful if anyone could offer any assistance in my project as I am unfamiliar with the statistics and what they mean.

The statistics can be found at http://mmedia.glos.ac.uk/students/mu...aAnalysis.zip.

Robert

Statistics

Hello Robert,

Clicking the link to your statistics brought up the ubiquitous "This page cannot be found". I looked at the stats you attached but without knowing the objective of your assignment none of them made sense.

I like the free stats calculator at statcrunch.com. However, some understanding of the basics of all those tools and techniques is mandatory to ensure that meaningful statistical inferences are obtained. Give me a link that works and I'll take another look.

Kind regards,

Jan W Merks

Hi Jan.

The actual link is http://mmedia.glos.ac.uk/students/mu...taAnalysis.zip but was the same as the attachment.

The scores relate to the following study.

I got 10 participant and put them into cricket nets. A coach scored each shot they performed out of 0-3 with 3 being the best. They then training and batted a second time. I then compared their performance scores per shot for each innings, before and after the training. This calculation produced improvement scores and show which participants improved more. I am comparing if the participants who training on a multimedia simulation improved more than the participants that trainined watching a coaching video.

I have attached the raw data and highlighted the performance scores in yellow.

Any suggestions on the statistics that I produced and how they relate to the study?

Regards

Rob

T-Test For Proportions

Hello Robert,

I looked at your data set and suggest you read the text under "t-test for proportions" on statcrunch.com. That application of the t-test allows you to compare probabilities before and after the learning stage.

Kind regards,
