STATISTICAL ANALYSIS AND RESULTS

This is the Data that we have obtained from our participants .

Variable	Data type
Length of foot	Scale
Length of forearm	Scale

The proposed statistical technique to test for H0 is Pearson's R as it involves in finding the relationship between two scale data type.

SCATTER PLOT

We will first examine the scatter plot to ascertain if the relationship is linear.

Fig1:Scatter plot

The scatter plot appears to follow a general positive linear trend.There is no violation of the linearity assumption.

a. Not assuming the null hypothesis. b. Using the asymptotic standard error assuming the null hypothesis. c. Based on normal approximation.

RESULTS:
There is positive,moderate and significant association between the length of the foot and the length of the forearm. (r=0.593, p<0.05, N=30) Since P<0.05, we reject H0 and conclude that there is a positive relationship between the length of the foot and the length of the forearm.

After knowing that there is a positive relationship between the length of the foot and the length of the forearm, we will now determine whether this relationship is the same for both males and females.

a. Not assuming the null hypothesis. b. Using the asymptotic standard error assuming the null hypothesis. c. Based on normal approximation. RESULT: There is a positive,moderate and significant associations between the length of foot and the length of forearm for male but not for female. The association for male is r=0.485,p=0.049<0.05,n=17. While the association for female is r=0.405, p=0.170>0.05 , N=13.  For male, since P<0.05 , we reject H0 and conclude that there is a positive relationship between the length of foot and length of forearm.  For female, since P>0.05 , we do not reject H0 and conclude that there is no positive relationship between the length of the foot and forearm . However, due to our small sample size with male and female participants <30 , our results may not be accurate.
