Symmetrical statistics

WebWhere the mean is bigger than the median, the distribution is positively skewed. For the logged data the mean and median are 1.24 and 1.10 respectively, indicating that the logged data have a more symmetrical distribution. Thus it would be better to analyse the logged transformed data in statistical tests than using the original scale.Figure 2.2 WebApr 2, 2024 · Figure 2.7. 1.
