Define digital, analog, and sampling

Digital describes electronic technology that generates, stores, and processes data in terms of two states: positive and non-positive. Positive is expressed or represented by the number 1 and non-positive by the number 0. Thus, data transmitted or stored with digital technology is expressed as a string of 0's and 1's.

Analog is defined as a watch that uses hands moving around the face of the watch to indicate time, rather than digital numbers. An example of analog is a watch where the big hand is on the 12 and the little hand on the 2.

In research terms a sample is a group of people, objects, or items that are taken from a larger population for measurement. The sample should be representative of the population to ensure that we can generalise the findings from the research sample to the population as a whole.
