Pros And Cons Of Being Left-Brained Dominant

Introduction
Throughout my life, I have always heard adults and other authority figures say, “That if your write with your right hand, you use the left side of your brain and if you write with your left hand, your use the right side of your brain.” I have always wondered about this say, but being an uninquisitive person and always respectful to my elders, I just believed what my elders had said and left it at that. However, as I have gotten old, I have begun to question whether or not that statement about being left-brained dominant or right-brained dominant is true because of the new things that became associated with being right-brained dominant or left-brained dominant.

According to Nielsen, Zielinski, Ferguson, Lainhart and Anderson 2013 study, their analysis was “…that an individual brain is not ‘left-brained’ or ‘right-brained’ as a global property, but that asymmetric lateralization…” (p.8). However, I still want to if what I have heard is true.
My goal with for my current study, is to help me to see whether the
A post hoc test “…compares each group with the every other group so you can see where the significance in overall F is coming from” (Adams and Lawrence, 2015, p.338). For each row comparison to have a significant F value, the difference between any two row means should have been greater than a 6.22. For there to be a significant F value for the columns, the difference between any two column means should have been greater than 11.38. In addition, when you looked at the cells, there should have been a difference of 19.71 between the means of any two
