Sensitivity

Sensitivity is the ability of a diagnostic test to detect disease. It is the proportion of individuals that test positive for a disease state as per the "gol.

Sensitivity is the ability of a diagnostic test to detect disease states.

Sensitivity is the ability of a diagnostic test to detect disease in a population. The diagnostic test is compared to the “gold standard” method of diagnosis.

Ratio is the highest level of measurement Ratio is the most informative Ratio characterised by equal intervals between variables Ratio characterised by a meaningful zero point Ratio example blood pressure Ratio example weight Ratio example money Ratio example time Ratio example height Ratio is interval data with a natural zero point Ratio permits comparisons being twice as high Ratio permits comparisons one-half as much  Ratio Data

Standard Error is SD of sampling distribution of a statistic Standard Error is important as it is used to compute confidence intervals  Standard Error is important as it is used to compute margins of error Standard Error is computed solely from sample attributes Standard Error is a measure of variability Standard Error is proportional inversely to the sample size Standard Error indicates how accurate estimate is likely to be Standard Error can be estimated by sample size Standard Error c

Wilcoxon Signed Rank Test is a non-parametric statistical hypothesis test Wilcoxon Signed Rank Test used when comparing two related samples Wilcoxon Signed Rank Test used as an alternative to the paired Student's t-test Wilcoxon Signed Rank Test does not assume normality in data Wilcoxon Signed Rank Test used when there are two nominal variables Wilcoxon Signed Rank Test used when there are one measurement variable Wilcoxon Signed Rank Test is based on median difference scores Wilcoxon

Mann-Whitney ‘U’ Test is a non-parametric test Mann-Whitney ‘U’ Test used to analyze data from 2 independent groups Mann-Whitney ‘U’ Test analyses the degree of separation Mann-Whitney ‘U’ Test is alternative to unpaired t-test Mann-Whitney ‘U’ Test outcome is not measured at a continuous level Mann-Whitney ‘U’ Test reports median of each group Mann-Whitney ‘U’ Test reports interquartile range of each group Mann-Whitney ‘U’ Test used when data is not normally distributed Mann-Whitney ‘U’
