Question

Describe the different types of research, clearly pointing out the difference between an experiment and a survey.

Answer 1

Answer:

Filter array C to keep only entries with values lower than next power of 2.

Scan input array once more and notice which of the intervals [2i .. C + 1] contain at least one input number: i = int_log(x) - 1; B[i] |= (x <= C[i] + 1).

Find first interval that is not filtered out on step #3 and corresponding.

Answer 2

Descriptive, correlational, causal-comparative/quasi-experimental, and experimental research are the four primary subtypes of quantitative research. The difference between experiment and survey are-

• The survey is a method for obtaining data from the populace's responders about a subject that is being studied. An experiment is a type of scientific technique where the variable being studied is isolated to test a hypothesis.
• Surveys are undertaken when the study is descriptive in nature, whereas experiments are carried out when the research is experimental.
• Particularly when the survey is carried out using postal questionnaires, the response rate is low, hence the survey samples are big. On the other hand, the number of samples needed for tests is usually rather minimal.
• Surveys are regarded as appropriate for use in social and behavioural research. Contrarily, experiments play a significant role in the physical and natural sciences.
• The term "field research" describes a study done away from a lab or office setting. The best type of field research is surveys. Experiment, on the other hand, is an illustration of laboratory study. A laboratory study is simply research conducted in a space outfitted with scientific instruments.
• Data gathering techniques used in surveys may include case studies, questionnaires, interviews, and observation. In contrast to an experiment, data from an experiment are gathered through many readings.
