BIO-3302 Lecture Notes - Lecture 1: Simple Linear Regression, Null Hypothesis, Allele Frequency
Document Summary
Hardy weinberg- a population that displays random mating and is not subject to any selective forces will not experience changes in allele frequencies over generations. Heritability (h2)- proportion of the total phenotypic variation that can be attributed to genetic variance. Measure of central tendency- mean, median, mode. Error in statistical tests, type 1- rejecting a true null hypothesis, type 2 - failure to reject a false null hypothesis, alpha- risking making a type 1 error, usually use = 0. 05. Sample size- usually the bigger the better, more representative. Sample range- cover the range of variation in the problem studied. Is there a correlation of functional relationship between two variables. A is y intercept, b is slope. Macroclimate- climatic variation over large spatial scales and long time periods. Growing degree days- used to estimate the growth and development of plants and insects during the growing season.
