"research hypothesis was there is a significant positive relationship between reports of sleep adequacy and the performance on a driving test. a positive correlation was found between the variables of self-reported sleep adequacy and performance on the driving simulator (r = 0.21, p = .37), although the correlation did not reach statistical significance."

The relationships among the variables are too weak to have practical application.

Explanation:

Here, the research hypothesis states that there is a significant positive relationship between reports of sleep adequacy and the performance on a driving test. However, one needs to look at the given r value to understand the correlation between the variables. Here, r value is reported to be 0.21 so it is a positive value but a weak one. R value needs to be over 0.3 at least to consider it a moderate correlation. Hence, it is a weak positive correlation. However, we also must look at the p value to establish its significance. P value need to be less than 0.05 in general to consider a result significant. Here, it is reported to be 0.37 which means that the relationship among the two variables is too weak to have practical application and is not significant to be considered for application.

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.
