Scientists who study climate have noted a series of marked changes that have gradually become increasingly evident during the last sixty years. Global climate change is the term used to describe altered global weather patterns, including a worldwide increase in temperature, due largely to rising levels of atmospheric carbon dioxide.

Population diversity may be measured in terms of the variation in genetic and morphological features that define the different populations.

It introduces binomial distribution, calculations for probabilities, means, variances, and confidence intervals, emphasizing sample size and independence. Applications include estimating the number of trials needed and using normal approximation for large samples. Key statistical methods discussed involve hypothesis testing and comparing proportions.

This concept is central to ecology: the study of adaptation is the study of the evolutionary relationship between organisms and their environment.

Population ecologists study what determines the occurrence and abundance of species in space and time: their geographic ranges, population sizes and densities, what factors result in them being so rare or common, and why these characteristics change over time.

It illustrates how sample means from normal and non-normal distributions behave, emphasizing reduced variance with increased sample size. Methods for evaluating normality using temperature data and calculating z-scores with Excel are discussed.
