DrBaker Designed an Experimental Study to Assess Potential Differences Between

Dr.Baker designed an experimental study to assess potential differences between science students and art students on a math reasoning abilities test.Dr.Baker found a mean difference in math performance between science and art students.On average, art students performed higher on the math reasoning test compared to the science students.Dr.Baker's results were supported in two other studies performed in university settings.Dr.Baker concluded that, given that the results of her study have been replicated at other universities, her findings were reliable.Dr.Baker also hopes that other researchers will perform the study using other samples including participants from the community.Dr.Baker is concerned about replicating her study across various settings and using additional samples because she wishes to:

A) improve the generalizability of her results.
B) support her null hypothesis.
C) improve her descriptive statistics.
D) calculate a probability.
