Decimation is an averaging method. When combined with oversampling, decimation improves the ADC resolution. In fact, adding 4p (4 power of p) ADC N-bit samples, gives a representation of the signal on N+2p bits. To have p additional effective b...

Choose a sampling method:Different methods can be used depending on the study's objectives. For example, random sampling focuses on fairness, whereas systematic sampling uses regular intervals. Determine the sample size:Thesample sizeneeds to be manageable and large enough to provide reliable results...
Learn how to calculate foot traffic in your retail store, with use cases and examples of what you can do with the data collected.
Types of Sampling Distributions There are three types of sampling distributions: Sampling Distribution of the Mean:This method shows a normal distribution where the middle is the mean of the sampling distribution. As such, it represents the mean of the overall population. To get to this point, ...
When should you choose sampling with and without replacement? Sampling with replacementis used because it allows us to use the same dataset multiple times to build models, instead of gathering new data, which often requires a lot of time and money. On the other hand,sampling without replacement...
Sampling errors occur when a probability sampling method is used to select a sample, but that sample does not reflect the general population or appropriate population concerned. This results in limitations of your study known as “sample bias” or “selection bias.” ...
Analysis Items: Discussion and examples of how to use and apply various aspects of analysis within SPM. Particularly helpful for beginners are the discussions about Contrasts and how they work. Concepts: Discussions of any of the above areas that are more theoretical and of a more general nature...
