Two fifth-grade math curricula are being studied. Two schools have agreed to participate in the study. One is randomly chosen to use curriculum A, the other to use curriculum B. At the end of the school year, the fifth-grade students in each school are tested and the results are used to do a statistical analysis comparing the two curricula. What criticism do you have of this experimental design? Explain!

Answer #1
  • This experimental design could lead to false justifications easily.
  • Suppose, children of school following curriculum A outsmarts children from school who followed curriculum B.
  • But, it can't be justified that curriculum A is better than B.
  • There might be other reasons related to the specific school like the teachers of school A might be good than the teachers of school B.
  • The resources available for the schools might vary.
  • So, it's not at all a good experimental design.

The goal of statistics is to use data to understand something about the world. To obtain useful results, a scientific approach should be followed. The basic approach can be summarized into a few steps. Write a question that can be answered by collecting data. Determine what variables to measure and how to collect a data sample. Analyze the data and create appropriate summaries. Create a report of the results, drawing conclusions or inferences where appropriate. For example, suppose you are...
