A Discussion on what we will be looking at
- A brief look at the table
- Summary Statistics for the Necessary Variables
Looking at the slope and graph for each linear model
- Delayed Flight vs Minutes of Late Arrival
- Delayed Flight vs Bagging Time
- Delayed Flight vs Time in security
Conclusions
- Which had the highest slope?
- Which had the highest correlation

Discussion

We want to take a look at 3 different variables and see how they affect arrival time.
Specifically we will be looking at how Flight Delay interacts with
- Late Arrival Time (in minutes)
- Baggage Loading Time (in minutes)
- Time in Security (in minutes)

Insight into data

Linear Analyses

For this section we will be looking at the different Linear Relationships Delayed Flight has with Baggage Loading, Late Arrival, and Security Time
We will also be recording the slope and correlation of the relationship

Delayed Flight vs Late Arrival

In this relationship, our flight Delay will increase by 24.56196 minutes for every 1 minute increase in Late Arrival. This relationship has a correlation of 0.66684

Delayed Flight vs Baggage Time

In this relationship, Flight Delay increases by 33.54257 minutes for every 1 minute increase in baggage loading time

Delayed Flight vs Security Time

As seen Below, time in security has no linear relationship with a Delayed Flight

Conclusions

After Looking at these 2 relationships, it is clear which one will be the best to model Flight Delay.
With both a higher slope and a higher correlation, we can see that Baggage Time will have more of an effect and increase in Departure Delay
