COURSE TITLE:Survey of Statistics (Statistics for non-math majors)
IAI CODE(S): M1 902
DELIVERY MODE:Online, In-Person


Focuses on statistical reasoning and the solving of problems using real-world data rather than on computational skills. Strong emphasis is on interpretation and evaluation of statistical results that arise from simulation and technology-based computations using technology such as the required TI83/84 Graphing Calculator with a built-in statistical package, and Microsoft Excel spreadsheets. Topics include data collection processes (observational studies, experimental design, sampling techniques, bias), descriptive methods using quantitative and qualitative data, bivariate data, correlation, and least­-squares regression, basic probability theory, probability distributions (normal distributions and normal curve, binomial distribution), confidence intervals and hypothesis tests using p-values.

This course is designed as a general survey of basic statistical methods. Emphasis is placed on methodology, and applications to biological, social, and management sciences are stressed to underscore the practicality of the material.

A student in this course should be college-ready in mathematics by having completed: Intermediate Algebra (MATH108) with a C or better, placement, co-requisite course, multiple measures, transitional mathematics competencies, or completing Applied Mathematical Concepts (MATH107) with a C or better.


Upon completion of this course, students will be able to:
  • Write, define and explain all statistical symbols and abbreviations used in the course
  • Clearly write interpretation of solutions to statistical application problems.
  • Show step-by-step work and provide explanation for how to both setup and generate a statistical solution for application problems.
  • Correctly make use of graphing calculators and /or spreadsheet software to complete statistical analysis.
  • Determine and state from any initial question the meaning and/or definition of all given statistics, and state what formulas and techniques will be used to generate solution.
  • Write or state definitions of, and be able to properly use in discussions (oral or written), basic statistical terminology.
  • Create statistical graphs from data by using technology.
  • Interpret and explain trends from statistical graphs.
  • Calculate basic statistics from data, both manually and by using technology.
  • Interpret and explain basic statistical information, with regard to patterns and outliers.
  • Apply basic probability concepts in calculations regarding probability distributions
  • Define and/or state the Empirical Rule.
  • Define and perform calculations on a normal distribution.
  • Define and perform calculations on a binomial distribution.
  • Graph, create, and perform calculations on linear models from data using regression techniques.
  • Differentiate between the Correlation Coefficient and the Coefficient of Determination.

  • Differentiate between Outliers and Influential Observations.
  • Calculate the population mean estimate through the use of confidence intervals.
  • Explain inferences and test hypotheses on population means using hypothesis tests with the Z and t test statistics
  • Explain the logical step-by-step setup, and solution process for statistical application problems clearly and precisely.
  • Clearly state the interpretation of a solution
  • Calculate answers to arithmetic and data oriented statistical problems using the TI series of statistical calculator and spreadsheet software

The student shall be evaluated on the basis of quizzes & homework (15%), Excel lab projects* (7%), major examinations (60 %), final examination (18%), and progress during the course.

Below 60%

*A minimum of 6 Excel projects will be chosen from the following:
WEEKLY LAB OUTLINE: Labs are designed to develop students’ critical thinking skills and give them hands-on practice at applying the concepts discussed in class, organizing and analyzing data, and drawing and writing conclusions. Excel software will be used.
  • Lab 1 – Intro & Bar Graphs/Pie Charts:
    • Students are given a brief introduction to lab policies and procedures and create a bar graph/pie chart from given data.
  • Lab 2 – Histograms:
    • Students create a histogram from a given distribution and use the graph to describe the shape, center and spread of the distribution.
  • Lab 3 – Time Plots:
    • Students make a time plot from data and use it to describe cycles and trends.
  • Lab 4 – Measures of Center and Spread:
    • Students calculate several statistics and use multiple graphs to do individual and comparison analysis on two or more distributions.
  • Lab 5 – Standard Normal Curve Calculations:
    • Students create a template for performing various calculations involving the standard normal curve.
  • Lab 6 – Scatterplots, Regression and Correlation:
    • Students use given data to create a scatterplot and perform multivariate analysis using regression and the correlation coefficient.
  • Lab 7 – Residual Plots:
    • Students perform further multivariate analysis with the use of a residual plot they create.
  • Lab 8 – Probability Distributions:
    • Students make discrete probability distributions and calculate probabilities for simple random experiments, such as the outcome of the roll of two dice.
  • Lab 9 – Law of Large Numbers:
    • Students make an inference and test it by performing an experiment a “large” number of times, making calculations and graphing the results.
  • Lab 10 – Sampling Distributions of the Sample Mean:
    • Students consider continuous distributions by forming multiple random samples, calculating their sample means and creating a distribution of those sample means.
  • Lab 11 – Central Limit Theorem:
    • Students make further discoveries of the result of a sampling distribution, which leads to the Central Limit Theorem.
  • Lab 12 – One-Sample z Confidence Intervals
  • Lab 13 – One-Sample z Significance Tests
  • Lab 14 – One-Sample t Confidence Intervals
  • Lab 15 – One-Sample t Significance Tests
