Congratulations! You've reached the final week of the course Understanding Clinical Research. In this lesson we will take a look at how good tests are at picking up the presence or absence of disease, helping us choose appropriate tests, and how to interpret positive and negative results.... Chi-Square Contingency Table Test A 2 (gender) x 3 (experimental condition) χ2 test was conducted to test the equal distribution of men versus women across experimental conditions. This analysis was and found to be statistically non-significant, χ2 (2,54) = .23, p < .89.

The unit covers the development of a suitable network design, the identification of relevant network components to meet the design brief and the installation, configuration and securing of the network to meet client requirements.... Contingency matrix and measures calculated based on it 2x2 contigency table for displaying the outcome of predictions. Based on the table it is possible to calculate row and column wise parameters, PPV and NVP, and sensitivity and specificity, respectively. These parameters are useful, but are not based on all the information in the table. Accuracy is a measure that is calculated based on all
