PYC3704 UNISA Assessment 1 3 Variables, Constants, and Sampling Data in Research

These are rough and ready, but may prove useful for studying for UNISA PYC3704 Assessment 1, and for the final exam. They are best viewed on a laptop or with the Study Guide open in front of you. I discussed the concept of variables and constants in research. Variables are measurements of constructs that can vary in value, while constants are numbers that always remain the same. I also explained the difference between dependent and independent variables, with the independent variable being the causal agent and the dependent variable being the one affected. Hidden variables were also mentioned, which are variables that may not be known or considered in calculations and measurements. I then moved on to discuss sampling data, where measurements from a whole lot of cases are called data. I also touched on the difference between descriptive statistics and inferential statistics, with descriptive statistics summarizing aspects of numerical data. I provided examples of how to calculate the mean, standard deviation, and correlation coefficient using mathematical notation.
