Question
Students are asked to state their attitudes towards statistics by responding to a series of questions. For each questions there are five response choices: 1=strongly agree; 2= agree; 3= neither agree nor disagree; 4 = disagree; 5= strongly disagree. What scale of measurement is represented by these responses? At a clean and jerk event at the Olympics, the heaviest weight lifted by each of the athletes was recorded. What scale of measurement is represented by the weight lifted? The best way to establish the existence of a causal relationship is to conduct an experimental study. There are three essential characteristics of an experimental study: 1. Control of variables not being studied, 2. Manipulation of the independent variable, and 3.__Explanation / Answer
1. This has been measured in ordinal scale. The data is a categorical variable, but since there is a ordinal relationship or particular order in between different levels of the data so this variable is measured in a ordinal scale.
2. This is a example of Interval scale.
3. Three principles of design of experiments are,
1. local control
2. replication
3. randomization
Hence, randomization is the answer.
Answer:
1. Ordinal
2. Interval
3. randomization
