P-Value Test Per BodySite (Ultralow against the world!)
========================================================


#reading from table file
```{r,echo=FALSE}
source("~/git/preservation_stats/scripts/distribution_test.R")
oral <- read.csv("~/git/preservation_stats/presv_fig1_data/oral_fig1.csv")
```

oral
--------------------

generating variables per Preservation Method:

```{r}
oral_ultralow = parse_vector(oral,1)
oral_nitrogen = parse_vector(oral,2)
oral_Phen_CL = parse_vector(oral,3)
oral_Fresh = parse_vector(oral,4)
```

Normality Test with Shapiro-Wilk Test :

```{r,echo=FALSE}
shapiro.test(oral_ultralow)

shapiro.test(oral_nitrogen)

shapiro.test(oral_Phen_CL)

shapiro.test(oral_Fresh)

```

Testing difference significance using Kolmogorov-Smirnov & Wilcoxon Test :
-----------------------------------------------------------------------------


```{r}
ks.test(oral_ultralow,oral_nitrogen)
wilcox.test(oral_ultralow,oral_nitrogen)
wilcox.test(oral_ultralow,oral_nitrogen,paired=T)

ks.test(oral_ultralow,oral_Phen_CL)
wilcox.test(oral_ultralow,oral_Phen_CL)
wilcox.test(oral_ultralow,oral_Phen_CL,paired=T)

ks.test(oral_ultralow,oral_Fresh)
wilcox.test(oral_ultralow,oral_Fresh)
wilcox.test(oral_ultralow,oral_Fresh,paired=T)
```
