Question

Place the following activities in their correct order:

1.) Designing an experiment that yields data

2.) Deciding how much data to collect

3.) Running the experiment that generates the data

4.) Collecting the data

5.) Interpreting the data to validate or discredit a model

Answer 1

The correct order will be

2-1-3-4-5

In the first step after we identify a problem or a question, we decide how much data and what type of data is needed to validate or reject our hypothesis or model.

In second step We plan that how we will be collecting the data. Which type of experiment we will be setting up. We also pay attention to feasibility of the experimental design in the given circumstances and available resources.

In the third step we run the experiment as planned, and observe the pattern

The fourth step involves proper collection of data and using proper statistical tools to reduce any sampling or data collection related error. The data should be fair and outliers must be removed from the data to avoid false inference.

The fifth and final step is the most important step. Here, we interpret the pre recorded data. The interpretation should be fair and without any bias. We should not try to fit in the data as per our pre concieved notion. After unbiased data analysis, We either accept (validate) or reject the hypothesis or model.
