Calculating the median lethal dose, LD50 (the dose of a toxin which kills half of the test population) first requires a lot of laboratory testing which can take months. The data is then accumulated and manipulated to give a value which is the median dose. -- Why don't you get to understand Lichfield wilcoxon's method.
The mean is that value that is most commonly referred to as the average.The typical value is a synonym for the mean and average.The typical value is the mean.
z-score of a value=(that value minus the mean)/(standard deviation). So if a value has a negative z-score, then it is below the mean.
The value is 0.3055
The mean is an estimated value because it is calculated based on a sample of data rather than the entire population. Sampling variability can cause the mean of a sample to differ from the true population mean. Additionally, the mean is sensitive to outliers and skewed data, which can further affect its accuracy as an estimate of the true population value.
