Representative Sampling Vs Experimental Research

When conducting research data is gathered from a sample. The data can prove or disprove the hypothesis. When reviewing the data, a person can become bias and only use the data that they feel is beneficial to their study. Rubin and Babbie (2014) write about the two types of sampling bias: Conscious and Unconscious. The authors state “When we speak of bias in connection with sampling, this simply means those selected are not typical or representative of the larger populations from which they have been chosen” (Rubin & Babbie, 2014).

Describe the experimental method, state its advantages and disadvantages, and distinguish between independent and dependent variables.

The researchers analyzed the data they collected as though it were at what level of measurement?

The compiled data was used to form population A of the experiment, while population B was predetermined and provided by the instructor. Research was conducted using primary sources and data collected in order to locate evidence supporting the hypotheses.

In this essay, I will appraise the sampling methods used in the following two case studies:

This is an observational study because it does involve the study of the variables as they are without any sort of manipulation.

In population-based studies, instead of looking at a small group of individuals to make an assumption on the entire population, we are taking numbers that represent the population and determining

Population and sample are two very important aspects to consider when conducting an experiment. The population is the whole group of individuals who are being studied, and the sample is a group of participants drawn from the population. Within Professor Unpopular’s experiment, the student body at a high school would be his population, and a group of forty students from a certain grade could possibly be his sample. Sample sizes can be very impactful on the results of an experiment. Typically, a larger sample size can give a better representation of the population rather than a smaller sample size. However this is not always the case, since sometimes a smaller representative sample is better than a bigger unrepresentative sample. The bigger, unrepresentative sample gives more chance for there to be biases, or even atypical individuals, which would ultimately give a worse reflection of the population. The independent and dependent variables are also extremely important factors in an experiment, since these variables allow for better observations and data to be collected. The independent variable is the variable that is manipulated by the

Since there is very little data, researchers often gather their own by using surveys, field experiments, and investigative reports from independent commissions

This research study used a convenience sample. A total of 58 undergraduate students, 27 males, and 31 females, who were enrolled in basic Communication classes at a South Texas University, agreed to participate in this study. Respondents were assured that their participation was anonymous and notified that the professor for the respective class approved this study. Each male and female respondent randomly assigned to one of the four self-report rating scales. Demographic information of the respondents such as sex, age, and year classification was asked but was not a qualification to be a participant.

The major advantage of observation studies over surveys, which obtain self-reported data from respondents, is that the data are free from distortions, inaccuracies, or other response biases due to memory error, social desirability bias, and so on. The data are recorded when the actual behavior takes place.
