Enumerative induction is an inductive inference involving generalizations based on a finite number of specific observations. It is a standard method used in scientific research and can help test hypotheses and make predictions. Enumerative induction is essential for inductive inference because it allows researchers and data scientists to draw general conclusions about a population based …
Science shapes our daily lives, from the detergents, food, and clothes we use to the medicines and machines we rely on. Basic science explains natural processes—how our bodies work, how plants grow, and how substances react—while applied science uses this knowledge to solve real-world problems. Pharmacists use biology and chemistry to create medicines, engineers apply …
In scientific research, we typically use hypotheses for our statistical analysis. A hypothesis is a good or educated guess that tries to explain how two or more things are related. It is a statement that makes a prediction when there is no hard evidence yet or just before we embark on an investigation. A researcher …
How can we draw or infer meaning from our surroundings? To do this, we depend on observation. But observation can take two forms: quantitative or qualitative. In research, quantitative observation is a type of observation that focuses on quantitative data. The word quantitative describes something that can be expressed in terms of quantity or numbers. …
Whenever you enjoy that coveted cup of tea, you should thank the process of sedimentation for the pleasure. The swirling of tea leaves which finally settle down to the bottom of the cup gives you that special flavor. While this may be a minor event like a storm in a teacup, the same process also …
How can you know if there is any connection between the variables in your dataset? Statisticians usually turn to a tool called linear regression. This involves a process that enables you to identify specific trends in your data. In linear regression, there is always an independent variable and a dependent variable. We use the independent …
A wide base and a pointed top, pyramids are three-dimensional shapes that feature a flat base and three or more triangular faces. The faces meet at a point (the top of the pyramid) forming the apex (the pointy top). The faces may be the same size or different sizes. The wide base of the pyramid …
A queue is an abstract data structure with a linear form that shows the order in which operations should be done. It is frequently used in computer science or programming to model real-life queue situations. A queue has certain special operations that can be performed on it. Enqueue: Store or introduce a new item to …
In statistics, researchers depend on hypotheses to make inferences. These are statements that assume that something about a population (a parameter) is true. But how confident are they that it is true? This is where hypothesis testing comes in… Hypothesis testing helps you to make an inference about if your specific findings are true or …
When a data point or observation falls outside the normal range, it is considered by data scientists as an outlier. They are what most people would simply refer to as being too big or too small in comparison to what is considered normal. Outliers are therefore considered to be rare or unusual occurrences. Outliers can …
