What is Elementary Statistics?




Statistics is the science of collecting, organizing, analyzing and interpreting data. Data can be numerical or categorical, quantitative or qualitative, discrete or continuous. Statistics can help us answer questions such as:


  • How many people voted in the last election?



  • What is the average height of students in a class?



  • What is the probability of winning the lottery?



  • What is the relationship between smoking and lung cancer?



  • How effective is a new drug in treating a disease?



Statistics can also help us make decisions based on evidence, test hypotheses based on data, and draw conclusions based on inference. Statistics can be applied to various fields such as business, education, health, social sciences, natural sciences and engineering.

What are the main topics covered in the book?




The book consists of 12 chapters, each covering a major topic in elementary statistics. The chapters are organized as follows:


Descriptive Statistics




This chapter introduces the basic concepts and techniques of descriptive statistics, such as types of data, levels of measurement, frequency distributions, histograms, stem-and-leaf plots, dot plots, bar graphs, pie charts, pareto charts, measures of central tendency (mean, median, mode), measures of variation (range, standard deviation, variance, coefficient of variation), measures of relative standing (percentiles, quartiles, z-scores), boxplots and outliers.


Probability




This chapter introduces the basic concepts and rules of probability, such as sample spaces, events, complement, union, intersection, mutually exclusive events, independent events, conditional probability, Bayes' theorem, counting techniques (fundamental principle of counting, permutations, combinations), and probability distributions (uniform distribution, empirical distribution).


Discrete Probability Distributions




This chapter introduces the discrete random variables and their probability distributions, such as binomial distribution (binomial experiments, binomial probability formula, mean and standard deviation of binomial distribution), geometric distribution (geometric experiments, geometric probability formula, mean and standard deviation of geometric distribution), Poisson distribution (Poisson experiments, Poisson probability formula, mean and standard deviation of Poisson distribution), and hypergeometric distribution (hypergeometric experiments, hypergeometric probability formula).


Normal Probability Distributions




This chapter introduces the continuous random variables and their probability distributions, such as normal distribution (properties of normal curve, standard normal distribution, normal probability plots), uniform distribution (properties of uniform distribution), exponential distribution (properties of exponential distribution), and normal approximation to binomial distribution.


Confidence Intervals




This chapter introduces the concept and methods of confidence intervals for estimating population parameters using sample statistics. It covers confidence intervals for population mean (when population standard deviation is known or unknown), population proportion (when sample size is large or small), difference between two population means (when population standard deviations are known or unknown), difference between two population proportions (when sample sizes are large or small), population variance and standard deviation.


Hypothesis Testing with One Sample




This chapter introduces the concept and methods of hypothesis testing for making decisions about population parameters using sample statistics. It covers hypothesis testing for population mean (when population standard deviation is known or unknown), population proportion (when sample size is large or small), population variance and standard deviation.


Hypothesis Testing with Two Samples




This chapter introduces the concept and methods of hypothesis testing for comparing two populations or groups using sample statistics. It covers hypothesis testing for difference between two population means (when population standard deviations are known or unknown), difference between two population proportions (when sample sizes are large or small), ratio of two population variances.


Correlation and Regression




This chapter introduces the concept and methods of correlation and regression for measuring and modeling the relationship between two quantitative variables. It covers scatterplots (patterns of association, outliers), correlation coefficient (properties of correlation coefficient, significance test for correlation coefficient), regression equation (least-squares method, slope and intercept interpretation), coefficient of determination (properties of coefficient of determination), prediction intervals and confidence intervals for regression line.


Chi-Squared Tests and the F-Distribution




This chapter introduces the concept and methods of chi-squared tests and F-tests for testing claims about categorical variables and variances. It covers chi-squared goodness-of-fit test (chi-squared distribution properties, chi-squared test statistic calculation, chi-squared test procedure), chi-squared test for independence (contingency tables, expected frequencies calculation, chi-squared test statistic calculation, chi-squared test procedure), chi-squared test for homogeneity (contingency tables, expected frequencies calculation, chi-squared test statistic calculation, chi -squared test procedure)


Nonparametric Tests




This chapter introduces the concept and methods of nonparametric tests for testing claims about ordinal or nominal variables. It covers sign test (sign test statistic calculation, sign test procedure), Wilcoxon rank sum test (rank sum calculation, rank sum test statistic calculation, rank sum test procedure), Kruskal-Wallis test (rank sum calculation, Kruskal-Wallis test statistic calculation, Kruskal-Wallis test procedure), and runs test (run count calculation, run count test statistic calculation, run count test procedure).

FAQs




  • What is the difference between descriptive statistics and inferential statistics?



Descriptive statistics is the branch of statistics that deals with summarizing and displaying data using graphs, charts, tables and measures. Inferential statistics is the branch of statistics that deals with making decisions and drawing conclusions about populations based on sample data using probability, confidence intervals and hypothesis tests.


  • What is the difference between a parameter and a statistic?



A parameter is a numerical value that describes a characteristic of a population. A statistic is a numerical value that describes a characteristic of a sample. For example, the population mean is a parameter, while the sample mean is a statistic.


  • What is the difference between a population and a sample?



A population is the entire group of individuals or objects that we want to study. A sample is a subset of individuals or objects selected from the population. For example, if we want to study the height of all students in a school, the population is all students in the school, while a sample is a group of students chosen from the school.


  • What is the difference between qualitative and quantitative data?



Qualitative data are data that can be categorized or classified into groups or labels. Quantitative data are data that can be measured or counted using numbers. For example, gender is qualitative data, while weight is quantitative data.


  • What is the difference between discrete and continuous data?



Discrete data are data that can only take certain values or have gaps between them. Continuous data are data that can take any value within an interval or have no gaps between them. For example, number of children is discrete data, while height is continuous data.
