Introduction to Minitab
This laboratory introduces students to the basics of the Minitab software. Students make use of a basic example (water consumption and temperature) to introduce students to manipulation of data, calculation of descriptive statistics, and creation of histograms.
Learning Objectives for Introductory Statistics
This text document lists detailed learning objectives for introductory statistics courses. Learning objectives are brief, clear statements of what learners will be able to perform at the end of a course.
Sampling from a Real Estate Database
This material is a detailed exercise for students in introductory statistics. Students are asked to collect a random sample of data from a real estate website; conduct descriptive statistics (including confidence intervals); and write a report summarizing their findings.
Star Library: What Makes the Standard Deviation Larger or Smaller?
The activity is designed to help students develop a better intuitive understanding of what is meant by variability in statistics. Emphasis is placed on the standard deviation as a measure of variability. As they learn about the standard deviation, many students focus on the variability of bar heights ...
Star Library: Regression - Residuals - Why?
As teachers of statistics, we know that residual plots and other diagnostics are important to deciding whether or not linear regression is appropriate for a set of data. Despite talking with our students about this, many students might believe that if the correlation coefficient is strong enough, these ...
Star Library: Which Paper Towel is More Absorbent?
This group activity focuses on conducting an experiment to determine which of two brands of paper towels are more absorbent by measuring the amount of water absorbed. A two-sample t-test can be used to analyze the data, or simple graphics and descriptive statistics can be used as an exploratory analysis. ...
Star Library: An Unusual Episode
Dawson (1995) presented a data set giving a population at risk and fatalities for an “unusual episode” (the sinking of the ocean liner Titanic) and discussed the use of the data set in a first statistics course as an elementary exercise in statistical thinking, the goal being to deduce the origin of ...
Star Library: Random Rendezvous
This activity leads students to appreciate the usefulness of simulations for approximating probabilities. It also provides them with experience calculating probabilities based on geometric arguments and using the bivariate normal distribution. We have used it in courses in probability and mathematical ...
The Central Limit Theorem
The applets in this section of Statistical Java allow you to see how the Central Limit Theorem works. The main page gives the characteristics of five non-normal distributions (Bernoulli, Poisson, Exponential, U-shaped, and Uniform).
The applet in this section allows for simple data analysis of univariate data. Users can either generate normal or uniform data for k samples or copy and paste data from another source to a text box. A univariate analysis is performed for all k samples.
The applets in this section allow users to see how probabilities and quantiles are determined from a Normal distribution. For calculating probabilities, set the mean, variance, and limits; for calculating quantiles, set the mean, variance, and probability.
The applet in this section allows you to see how the T distribution is related to the Standard Normal distribution by calculating probabilities. The T distribution is primarily used to make inferences on a Normal mean when the variance is unknown.
Science as Investigation: A First Majors Course Teaching the Process
The first laboratory course biology majors take should challenge their expectation that biology is the mere memorization of knowledge. Rather, it should introduce them through experience to the scope and limitations of scientific investigation. Following a brief introduction to epistemology and the nature and goals of science, this course provides students with a developing understanding of scientific thinking, methodology, and experimental design. During the final unit of the course students de
Using Chromosome Kits to Assemble Human Karyotypes
This exercise provides a hands on introduction to the preparation of human karyotypes. Students practice karyotype preparation using Biophotos of normal male and female chromosome smears. The students then prepare a karyotype using a Biophoto of chromosomes from a Down syndrome individual or from a Down syndrome carrier.
Using Handheld Wireless Computers to Increase Interactivity and Collaborative Learning in Large Clas
We conducted a pilot study to determine the effectiveness of wireless, handheld computers in fostering active and collaborative learning in lecture-based teaching. We compared the capabilities of the largest type of handheld, the Jornada 820, to that of the smallest, a Handspring Visor "personal digital assistant." This article describes our use of the handhelds in a variety of classroom exercises, emphasizing wireless internet access. We explain our successes, problems, and proposed solutions.
When Do Adaptive Mutants Arise in Yeast?
This exercise examines when adaptive mutations arise in a population. Students prepare cultures of baker's yeast on normal agar media and then transfer the exact spatial pattern of these colonies to agar plates containing copper using the replica-plating technique. They compare the pattern of mutant ...
Vietnam: Journeys of Body, Mind, and Spirit
This Web site, created to complement the Vietnam: Journeys of Body, Mind, and Spirit exhibit, includes the following sections: Introduction is an overview of the incredible diversity of Vietnam's people and landscapes; Journeys Through Time and Space provides a look at Vietnam today and a time-line of this ancient country's history; Journeys of Gods, Families and Ancestors considers the importance of lunar New Year and the ancestral altar; Journeys of People and Goods examines how international
A Seasonal Guide to New York City's Invertebrates
This engaging illustrated guide gives an introduction to the local invertebrates one can see in various habitats of New York City and offers suggestions for where and when to search for them, along with information on how best to protect them. The Seasonal Guide is being distributed at no charge throughout the City to parks, nature centers, and other organizations involved in public education and conservation.
Kids' Guide to the Birds of Central Park
An illustrated guide to birds commonly found in Central Park, and an introduction to birding for young naturalists. The guide also includes information on where to go in Central Park to see birds in various habitats: freshwater, woodlands, and open areas.
