Power Flow and Efficiency - University of Sussex

Mechanical efficiency losses • Friction losses in the engine come from friction between moving parts (such as the piston rings on the cylinder walls), the power required to run the valve gear and the pumps and the pumping losses involved in getting the gases in and out of the cylinder. A large part of the work appears as heat in the coolant ...

Table of critical values for the F distribution (for use with ANOVA): How to use this table: There are two tables here. The first one gives critical values of F at the p = 0.05 level of significance.

Using SPSS, Handout 2: Descriptive statistics

Research Skills One: Using SPSS 20, Handout 2: Descriptive Statistics: Page 1: Using SPSS 20: Handout 2. Descriptive statistics: An essential preliminary to any statistical analysis is to obtain some descriptive statistics for the data obtained - things like means and standard deviations. This handout covers how to obtain these.

He lives in Ibiza, working as a tour guide. He has killed 8000 people. These days his preferred method is to lock the disco doors and then slaughter everyone inside, drinking about seventy pints of blood at a time. (It's a small disco). He gives human blood a rating of "7" on the tastiness scale. He drinks four times a

The Wilcoxon test - University of Sussex

Wilcoxon test is unusual in this respect: normally, the BIGGER the test statistic, the less likely it is to have occurred by chance). This handout deals with using Wilcoxon with small sample sizes. If you have a large number of participants, you can convert W into a z-score and look this up instead. The same is true for the Mann-Whitney test.

Table of critical values for the Wilcoxon test

Wilcoxon's test statistic to the critical value in the table (taking into account N, the number of subjects). Your obtained value is statistically significiant if it is equal to or SMALLER than the value in the table. e.g.: suppose my obtained value is 22, and I had 15 participants.

DAST-10: Drug Abuse Screening Test - GHC

DAST-10 Introduction The Drug Abuse Screening Test (DAST-10) is a 10-item brief screening tool that can be administered by a clinician or self-administered. Each question requires a yes or no response, and the tool can be completed in less than 8 minutes. This tool assesses drug use, not including alcohol or tobacco use, in the past 12 months.
