Chapter 1: Problem 2

Briefly explain the types of statistics.

Short Answer

Expert verified
Statistics is divided into two main types: Descriptive statistics, which summarizes and organizes data in a meaningful way and can be visually represented using graphs and charts; and Inferential statistics, which allows us to infer trends about a larger population from our sample, using methodologies like linear regression models, ANOVA, chi-square etc.

Step by step solution

01

Explain Descriptive Statistics

Descriptive statistics is concerned with summarizing and organizing the data in a meaningful way. It provides simple summaries about the sample and the measures. These sums and measures are typically numerical figures such as average, percentage, etc. Descriptive statistics are broken down into measures of central tendency (mean, median, and mode) and measures of dispersion or variability (range, variance, and standard deviation). Also, with graphic representations like graphs and charts, data can be presented visually.
02

Explain Inferential Statistics

Inferential Statistics, on the other hand, is used to make judgments of the probability that an observed difference between groups is a dependable one or one that might have happened by chance in this study. Thus, inferential statistics lets us infer trends about a larger population from our sample. Common examples of inferential statistics include linear regression models, ANOVA (Analysis of Variance), chi-square etc.

In which sampling technique do all samples of the same size selected from a population have the same chance of being selected?

A pharmaceutical company has developed a new medicine for compulsive behavior. To test this medicine on humans, the physicians conducting this study obtained a list of all patients suffering from compulsive behavior who were being treated by doctors in all hospitals in the country. Assume that this list is representative of the population of all such patients. The physicians then randomly selected 1820 patients from this list. Of these 1820 patients, randomly selected 910 patients were assigned to the treatment group, and the remaining 910 patients were assigned to the control group. Neither patients nor doctors knew what group the patients belonged to. Six months later the conditions of the patients in the two groups were examined and compared. Based on this comparison, the physicians concluded that this medicine improves the condition of patients suffering from compulsive behavior. a. Is this an observational study or a designed experiment? Explain. b. Is this a double-blind study? Explain.
