A student recently wrote us: "This question was a little confusing to solve because there was "significance" given on only figure 1, and i figured that meant that the rest of the graph findings were not significant."
It is important to note that significance doesn't make a result or difference true. Statistical significance gives the reader an indication of the probability that what was observed was due to random sampling error. The point at which a result becomes statistically significant is an agreed upon number that researchers have determined as a point to safely state something is statistically significant. A difference that is not statistically significant can still be used to lend strength to a working conclusion. In essence, don't automatically dismiss differences in results on the MCAT because they are statistically significant. Here is an interesting article that discusses the use of p-values in research published in Nature: https://www.nature.com/articles/d41586-019-00857-9
Thanks for your question. I hope this helps!
