An experiment wants to find the wind speed that begins to lift an airplane. the strategy is to use a 1/32 scale model and wind tunnel. why is this strategy valid?
a. a wind tunnel is available for the experiment.
b. the real airplane will not fit in the wind tunnel.
c. the scale model matches the scale of the physical forces in the wind tunnel.
d. an inexpensive scale model of the airplane is available through the local hobby shop.

c. The scale model matches the scale of the physical forces in the wind tunnel.

Data’s conclusion is considered valid if the experiment validity is being controlled. With this conclusion validity, our data gathered and presented are considered a reasonable one. It is the most important types of validity. As what is said, by having conclusion validity, your data will be undoubtedly least considered since it is labelled as statistical and well-studied. Once you already mention the word statistics meaning it is studied and surveyed with the most of the human race and includes relationship in your data.
