Hello everyone,
I wanted to share an update on the progress of my research project. I am
investigating the primary contributors to aircraft delays at DFW airport,
utilizing data provided by the United States Department of Transportation
(USDOT): Causes of National Aviation System Delays
Dallas/Fort Worth, TX: Dallas/Fort Worth International (January - December,
2022). The dataset comprises information on flight delays, cancellations, on-
time performance, air traffic statistics, and seasonal variations.
My objective is to analyze this dataset to uncover factors contributing to
aircraft delays at DFW airport, with a specific focus on understanding how
these factors vary across different seasons. I have identified key variables for
my analysis:
1. Flight Delays: I will be examining the `arr_del15` column, which represents
the total number of flights delayed by 15 minutes or more.
2. Weather-Related Delays: While the dataset doesn't explicitly categorize
weather-related delays, I will use the available information in columns such
as `weather_ct` to understand the impact of weather on delays.
3. Seasonal Categories: Although the dataset lacks a dedicated column for
seasons, I plan to derive this information from the `month` column, grouping
months into seasons to assess seasonal variations.
4. Airline Information: I will explore the impact of different airlines using the
`carrier` and `carrier_name` columns.
5. Air Traffic Volume: The `arr_flights` column will serve as a proxy for air
traffic volume, allowing me to explore correlations between delays and
varying levels of air traffic.
I am currently in the process of navigating the USDOT website to ensure the
data's availability and format. Simultaneously, I am formulating a strategy
for data cleaning and processing to ensure the accuracy and reliability of my
research findings. As part of this process, I am considering the following:
1. Research Questions: What are the primary factors contributing to aircraft
delays at DFW airport, and how do these factors vary across seasons?
2. Hypotheses:
Research Hypothesis:
?
1: Flight delays at DFW airport are influenced by seasonal variations, with
certain seasons experiencing more delays than others.
Null Hypothesis:
?
0: There is no significant difference in flight delays at DFW airport across
different seasons.
3. Statistical Tests: I am evaluating the most appropriate statistical tests for
my study. In this case, a suitable statistical test would be ANOVA (Analysis of
Variance). ANOVA can help me determine whether there are statistically
significant differences in the means of flight delays across different seasons.
It allows us to compare means across multiple groups (seasons)
simultaneously.
If anyone has insights or suggestions, especially regarding the analysis of
weather-related delays, hypotheses formulation, or the choice of statistical
tests, I would greatly appreciate your input.
Looking forward to your thoughts!
