Simple random sample

feature of reliability which applies to differently worded items for measuring the same variable. Jupp (2006) also called this the “split half method” because it can measure variables of items being administered to the same sample at different points in time, or two sub-samples at the same point in time. The third feature is the internal consistency reliability which comprises of using groups of items to assess or measure different aspects of the same concept. Furthermore, it has also been…

before and after receiving mindfulness training based on the theory of planned behaviour and social cognitive theory. The survey data was used to measure change in the students level of mindfulness before and after the training compiled with a paired sample test, which resulted in an measurable outcome.

Agarose Gel Electrophoresis Since the discovery of the four classes of macromolecules (proteins, lipids, carbohydrates, and nucleic acids), researchers and biochemists have fine-tuned methods that reveal structural information about each of them. Different structural properties determine different functions and chemical properties, and scientists have developed intricate techniques to observe, quantify, and isolate molecules based on their aforementioned properties. Agarose gel electrophoresis,…

The title that was selected is a basic, simple explanation of what the article holds, instead of an eye-popping draw to read the article. In my opinion, the title would not have drawn me into read the article if I was just doing a random search. Thankfully, my specific search criterion…
