Distributions, Sampling and Estimation Our main objective in this section is to learn how to estimate some important characteristics of random variables using data. We will concentrate on estimating the mean from a normal distribution, and the proportion of success in a binomial distribution. To talk about estimation, we first need to know something about distributions and sampling. Most data used for decision making exhibit variation. We are interested in drawing conclusions

Statistics Chapter 2 Methods for Describing Sets of Data Quantitative data is information about quantities; that is, information that can be measured and written down with numbers. Qualitative data is information about qualities; information that can't actually be measured. A class is one of the categories into which qualitative data can be classified. The class frequency is the number of observations in the data set that fall into a particular class. The class relative frequency is the class
