Non-normal distributions- Bimodal- Positive skew- Negative skew - Bimodal (2 diff populations i.e. fast vs slow acetylators)- Positive skew (longer tail on the right, mean > median > mode)- Negative skew (longer tail on the left, mean < median < mode)So median often reflexts central...
It cannot be applied to distributions of other shapes Normal curve All Normal distributions are the same if we measure in units of size σ from the mean μ as center. Changing to theses unites requires us to standardize, just like we did in the last section, using z= x-μ/σ. If the...
