Activty 2: Write as many as you can the things that are considered variables found in school campus. (1 Whole paper) for 3 minutes and present to the class.) *The winner will have the most number of variables. A variable varies and has values. The values of variables under study are the research data. Variables Are these variables? chair, shape of table, tweet, shirt style. KINDS OF VARIABLES: NATURE OF VARIABLE &DATA Nominal scale is characterized by data that consist of names, labels, or categories only. Ordinal scale involves data that may be arranged in some order but Variables differences between data values either cannot be determined or meaningless. Interval scale is data for which we can determine meaningful amounts of differences between data. However there is no inherent zero starting point. Zero exists. Ratio scale is the interval scale to include the inherent zero starting point. For these values, differences and ratios are both meaningful. Zerodoesn’t exist Examples: 1. Nominal – Gender, Hair color, type of living accommodation (apartment, condo etc), Genotype (Bb, bb, BB), Religion, civil status 2. Ordinal – High school class ranking, socio-economic status, likert scale, level of agreement (Yes, maybe, no), time of the day (Dawn, morning, noon), Political orientation (left, center, right) 3. Interval – (Temperature, Fahrenheit, IQ, Time on a clock) 4. Ratio – age, weight, height, sales figures, income, years in education and number of children) Other types of variables: 1.Independent variable – manipulated by the researcher (X-axis) 2. Dependent variable – one which changes as a result of the independent variable being changed (Y-axis) Promotion affects employees’ motivation Promotion – IV Employees’ motivation - DV 3. Intervening/Mediating Variable ▷ It is a variable whose existence is inferred but it cannot be measured. ▷Determining the effect of video clips on learning ability of students of M.Phil. ▷ Such as anxiety, fatigue, motivation, improper diet ▷Higher education typically leads to high income ▷ Better occupation – intervening variable 4. Control/Constant variable is a variable that is NOT allowed to be changed unpredictably during an experiment. (remain the same) ▷ How electricity affects experimental subjects ▷ Voltage from a power supply – constant (energy supplied will be changed if not constant) ▷ It • • ACTIVITY 3 Which goes where?
