Cognitive Fun Visual Digital Span Case Study Analysis

Research Question 1:

Is there a statistically significant relationship between the forward percent correct and backward percent correct?

Null Hypothesis:

There is a statistically significant relationship between the forward percent correct and backward percent correct.

Alternate Hypothesis:

There is not a statistically significant relationship between the forward percent correct and backward percent correct.

The correlation table of the document is showing the p value of 0.000, which is lower than the 5 percent significance level and provides the strong statistical evidences to reject null hypothesis, stating that there is a statistically significant relationship between the forward percent correct and backward percent correct to conclude that there is not a statistically significant relationship between the forward percent correct and backward percent correct.

In addition to this; the Pearson correlation value is 0.609, which shows that there is a slightly higher than the medium positive correlation between the forward percent correct and backward percent correct. It also concludes that if the value of the forward percent correct increases; it will also increase the value of the backward percent correct and vice versa.

Research Question 2:

Is there a statistically significant relationship between the forward time and backward time?

Null Hypothesis:

There is a statistically significant relationship between the forward time and backward time.

Alternate Hypothesis:

There is not a statistically significant relationship between the forward time and backward time.

The correlation table of the document is showing the p value of 0.001, which is lower than the5 percent significance level and provides strong statistical evidences to reject the null hypothesis, which states that there is a statistically significant relationship between the forward time and backward time and to conclude that, there is not a statistically significant relationship between the forward time and backward time.

In addition to this, the Pearson correlation value is 0.431, indicating that that there is a medium positive correlation between the forward time and backward time, which concludes that if the value of the forward time increases; it will also increase the value of the backward time and vice versa.

Discussion

Cognitive tests have been performed. The assessment measured three cognitions: attention, memory and executive function. Attention span tests the ability to complete and think sensibly. This also tests how easily you are distracted. The memory span shows how different memories have been impaired. The exceptive function helps the mental process.This test has diagnosedthemental health conditions. To test the mental health condition of someone;a cognitive test is an appropriate option. The results and explanations of the test into the methodology of digit span testsare presented. The same test method can be used in experiments of groups irrespective of the differences in visual angles. The test also requires a sequence of information as it is important to remember and enter the information. This is a task that checks verbal ability and it is also included in IQ tests. All these calculations showed the results of their respective area. The test results show the mean, median, variance, and standard deviation. Pearson relationship esteem is 0.431, which shows that there is a medium positive correlationbetween the forward time and in reverse time, the reason behind which is that if the estimation of the forward time will expand, it will likewise build the estimation of the regressive time and the other way around......................................
