Correlation Analysis

Biomechanics of ligament and relationship between age, diagnosis and histology.

The aims were to determine whether there is a link between histology. That is SMA, EVG and MT and the other parameters. And a link between the histological parameters in themselves.

Hypothesis: young's modulus and/or yield and/or strain is related to age/diagnosis/histology

The samples are from ligaments removed from patients after surgery.

1. is there a correlation between age and any of the other variables

2. is there a correlation between diagnosis and any of the other variables

3. is there a correlation between EVG,SMA or MT independent of other factors

4. Is there a correlation between the strain, yield or youngs and any of the MT, EVG and SMA

5. Is there a correlatin between youngs, yield and strain and age or diagnosis

6. Is there a correlation between duration of symptoms and SMA irrespective of other factors

1. Is there a correlation between age and any of the other variables

The correlation between age and other variable are given below. The significance of correlation is also tested .
The null hypothesis considered is H0: r =0 Vs H1 : r ≠ 0
The test statistics used is . The conclusions are taken based on the p value. If p value is less than 0.05 , we reject ...
