Course Software
Participants will use SPC XL DEMO, an Excel add-on that facilitates the creation of control charts, histograms, Pareto charts, box plots, and more. It also supports various statistical tests, such as the t-test and the F-test. SPC XL seamlessly integrates into Excel, appearing as a menu item on the toolbar. The generated charts and statistics remain within standard Excel workbooks, enabling easy sharing with anyone using Excel—even without SPC XL. This feature is crucial for maintaining dynamic, updatable control charts without recreating them.
Learning Objectives
By the end of this course, participants will be able to:
Understand and Define Key Concepts
Grasp fundamental terms like null hypothesis, alternative hypothesis, alternate hypothesis, and statistical significance. Learn to distinguish between the true and false null hypotheses, setting the stage for robust statistical analysis.
Perform Hypothesis Tests
Apply the correct hypothesis testing formula to perform statistical tests such as the t-test, chi-square test, and others tailored to various scenarios, including tailed hypothesis testing and two-tailed hypothesis testing. You’ll use actual random population samples and categorical variables to simulate true-to-life data analysis conditions.
Interpret Test Results
Develop the ability to analyze test statistics, interpret p values, and understand significance levels. This includes assessing the implications of type I and type II errors and suggesting insufficient evidence or statistically significant differences where applicable.
Make Informed Decisions
Based on the insights derived from hypothesis tests on a statistical sample or independent variable, learn how to determine if there is enough evidence to reject a hypothesis statement or if a false positive or false negative could influence decision-making.
Deep Dive into Data Collection and Analysis
Master the process of collecting data, setting up a research hypothesis, and choosing the right-tailed test or right-hypothesis test for your study. Learn how hypothesis testing works with dependent variables and multiple groups, understanding the role of sample size and population standard deviation in shaping research outcomes.
Advanced Interpretations
Evaluate the implications of observed data, initial hypothesis, and hypothesis tests across two competing hypotheses. Understand how to use statistical inferences and sampling distribution in data analysis, recognize the default assumption, and know when an error occurs in hypothesis testing.
This comprehensive approach will equip you with the skills to perform hypothesis testing and statistical tests based on collecting data and analyzing it to draw significant conclusions in research and professional settings.
What’s Included
- Comprehensive course materials, including slides, case studies, and a hypothesis testing quiz.
- Access to statistical software tools for practical application.
- Guidance and support from experienced statistical analysts.

What did you like most? “the coaching session and videos, the possibility to stop the video if something is not clear”
Lisa was really the best. Also, videos were really good – Thanks to Lisa and Mark! “
“The online courses can be taken within the time frame that suits for my daily work. Yet, there are scheduled virtual sessions setting the milestones.”
“I thought this would be training like all the rest, I was very wrong. I found the instructor to be very interesting and captive with what could be thought of as dry data. He did not read from a power point, did not teach strictly from a book, but provided information that got me excited about making a difference in our operation which ultimately improved the bottom line. I was not trained only, but was given the opportunity to certify, which verified I understood the training.”

FAQs
What is hypothesis testing?
Hypothesis testing is a statistical method used to infer population parameters from a random sample or random population sample. The goal is to determine whether the observed effects reflect a statistically significant difference using methods such as calculating the p-value and analyzing test statistics.
How do I choose the right hypothesis test?
Selecting the proper hypothesis test depends on your specific research question, the type of data you have, and what you aim to measure. This course will guide you through choosing the appropriate test, whether it’s a two-tailed test for a dependent variable or another scenario, ensuring robust and valid results.
What if my data does not meet test assumptions?
If your data deviates from normal assumptions, this course offers strategies to manage it, including data transformations and non-parametric tests. These methods help maintain the validity and reliability of your statistical tests, even when typical data conditions aren’t met.
How does the concept of a random sample impact hypothesis testing?
A random sample is crucial in hypothesis testing. It ensures that the data represents a larger population without bias, allowing for accurate inferences about the population parameter. This course covers collecting and utilizing random samples effectively, ensuring your hypothesis tests reflect true population characteristics.
Why is it important to understand the significance of a statistically significant difference?
Understanding what constitutes a statistically significant difference allows researchers to make informed decisions about the validity of their hypothesis tests. This concept helps differentiate between effects likely due to chance versus those indicative of actual differences or relationships in data science. The course will explore how to interpret and apply these differences in practical, data-driven scenarios.
