The soundness of research is established on orthodox application of tested and justified research methods and reporting all findings accordingly. The principle of scientific soundness is about proper design of a study as well as it must be executed with sufficient skills and rigour. Soundness is also about research ethics as only research ...

Nov 10, 2017 · A key feature of research that is scientifically sound is adequate replication of the data. The results must be reproducible, that is there must be sufficient replication - this means experimental replication not just technical replicates of the same experiment - to provide confidence that the observations are not due to chance.

By definition, an experiment is a procedure that tests a hypothesis. A hypothesis, in turn, is a prediction of cause and effect or the predicted outcome of changing one factor of a situation. Both the hypothesis and experiment are components of the scientific method. The steps of the scientific method are: 1. Make observations. 2. Ask a question or...
The two key parts of an experiment are the independent and dependent variables. The independent variable is the one factor that you control or change in an experiment. The dependent variable is the factor that you measure that responds to the independent variable. An experiment often includes other types of variables, but at its heart, it’s all abo...
Fertilizer and Plant Size
For example, you think a certain fertilizer helps plants grow better. You’ve watched your plants grow and they seem to do better when they have the fertilizer compared to when they don’t. But, observations are only the beginning of science. So, you state a hypothesis: Adding fertilizer increases plant size. Note, you could have stated the hypothesis in different ways. Maybe you think the fertilizer increases plant mass or fruit production, for example. However you state the hypothesis, it inc...
Salt and Cookies
You don’t need a lab for an experiment. For example, consider a baking experiment. Let’s say you like the flavor of salt in your cookies, but you’re pretty sure the batch you made using extra salt fell a bit flat. If you double the amount of salt in a recipe, will it affect their size? Here, the independent variable is the amount of salt in the recipe and the dependent variable is cookie size. Test this hypothesis with an experiment. Bake cookies using the normal recipe (your control group) a...
Based on the examples of experiments, you should see what is notan experiment: 1. Making observations does not constitute an experiment. Initial observations often lead to an experiment, but are not a substitute for one. 2. Making a model is not an experiment. 3. Neither is making a poster. 4. Just trying something to see what happens is not an exp...
There are three main types of experiments: controlled experiments, natural experiments, and field experiments, 1. Controlled experiment: A controlled experiment compares two groups of samples that differ only in independent variable. For example, a drug trial compares the effect of a group taking a placebo(control group) against those getting the d...

Sound is a type of energy made by vibrations. When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules. This “chain reaction” movement, called sound waves, keeps going until the ...
Should we review for soundness, as a pose to reviewing for soundness and importance. How can we construct a review process that is scientifically sound? The first thing you would do in a scientific process is to look at the evidence, but Neylon believes the evidence is almost totally lacking for peer review.
When possible, scientists test their hypotheses using controlled experiments. A controlled experiment is a scientific test done under controlled conditions, meaning that just one (or a few) factors are changed at a time, while all others are kept constant. We'll look closely at controlled experiments in the next section.
