## `summarise()` regrouping output by 'Class' (override with `.groups` argument)
Females Seem/tend to be the brightest in this dataset, however to be a little bit thorough let us examine to just what account is the relationship between variables in our dataset using Correlation.
Correlation Analysis is only possible for Numeric Variables, so we first have to encode our Factor Variables accordingly.

As you can see the data does not seem to make sense with all these repetitve jargons, now we will retrace our steps and work with creating a pairwise correlation in only Numeric Values and observing their p-values against our Outcome Variable in a graph, we will reserve encoding for more complex matters.
crr_valid <- cor(numericVars, use = "pairwise")
kable(round(crr_valid, 2))
| raisedhands | VisITedResources | AnnouncementsView | Discussion | |
|---|---|---|---|---|
| raisedhands | 1.00 | 0.69 | 0.64 | 0.34 |
| VisITedResources | 0.69 | 1.00 | 0.59 | 0.24 |
| AnnouncementsView | 0.64 | 0.59 | 1.00 | 0.42 |
| Discussion | 0.34 | 0.24 | 0.42 | 1.00 |
library(ggcorrplot)
ggcorrplot(crr_valid,
hc.order = TRUE,
type = "lower",
lab = TRUE)
The highlight of this Pairwise Correlation is that all of our Numeric Variable have a positive Relation with themselves, the next step is to see how they particularly relate to the Outcome Variable, testing with P-Value, i.e where in our case we set a 0.05 level of significance that a value below this would indicate a significant Relationship and vice versa.
## Append and Encode Outcome Variable to Numeric Variables
numericVars$Class <- edu_Df$Class
## nested condition for encoding
numericVars$Class <- ifelse(numericVars$Class == "H", 3,
ifelse(numericVars$Class == "M", 2, 1))
## Correlation On Class
crr_outcome <- cor(numericVars, use = "pairwise")
kable(round(crr_outcome, 2))
| raisedhands | VisITedResources | AnnouncementsView | Discussion | Class | |
|---|---|---|---|---|---|
| raisedhands | 1.00 | 0.69 | 0.64 | 0.34 | 0.65 |

| Class | 0.65 | 0.68 | 0.53 | 0.31 | 1.00 |
## Visualize the Relaitonship ~ P-Value
crr_outcome %>%
corrplot(method = "color", type = "lower", tl.col = "black", tl.srt = 45,
p.mat = cor.mtest(crr_outcome)$p,
insig = "p-value", sig.level = -1)
VisitedResources variable here seems to be the biggest PRedictor of a Student’s Grades.
Now let us turn our Focus on Factor Variables - Keep in my that our Outcome Variable is a Ordinal Categorical/Factor vARIABLE, and the Chi Sq Test is excellent for small sample, CAT on CAT statistical Analysis.
