Examples: Statistical analysis of data enables us to make important decisions in real-life situations. Statistical analysis is used in all aspects of life and business to evaluate the patterns in data to explore

Even the greatest findings seem very trivial – looking back at them a few days later. You feel that this outcome was so logical. You should have known this the whole time. When you are presenting the results of your 1-month data analysis project, there will be always someone in the roo...
This article is a practical introduction to statistical analysis for students and researchers. We’ll walk you through the steps using two research examples. The first investigates a potential cause-and-effect relationship, while the second investigates a potential correlation between variables. Example:...
Statistical significance is important when assessing the results of statistical analysis, but you also need to look at the actual statistic values involved and decide whether they are practically significant, with meaningful real-world implications. ...
Statistical fallacies are common tricks data can play on you, which lead to mistakes in data interpretation and analysis. Explore some common fallacies, with real-life examples, and find out how you can avoid them. Download poster Cherry Picking ...
Knowledge of the frequencies of synonymous triplets in protein-coding and non-coding DNA stretches can be used in gene finding. These frequencies depend on the GC content of the genome or parts of it. An example of interest is provided by stop codons. Th
However, sometimes they are “real,” and no corrections can be made, and they certainly cannot simply be discarded and may therefore pose a problem. 4.5.2 Detection of Violations The exploratory data analysis techniques presented in Chapter 1 should be used as a matter of routine throughout ...
Detailed analyses of more than 40 real-life examples from medicine, health, and the social sciences A separate chapter on sample size calculations In-depth treatment of meta-analysis Each chapter ends with recommendations for practical use
These are only a few examples of decision problems in education. For a long time, these problems were faced without any decision-theoretical backing. However, current research in education, specifically on test design, involves decision theory as a basic resource. As discussed by van der Linden ...
