Abstract
For my research project, I have been studying the pack weights for a number of teams
in the Aviva rugby premiership to see if there is a relationship between the pack
weights and the number of scrums that team is able to win in a single game and if
they can maintain this success throughout the season. This project meant I had to
compile data from a number of different website and organise into a table from which
I would gather my data from once I started to analysis the matches. This research
project was all to be conducted as desk research, as an observational task, as all I was
doing was collecting quantitative secondary data and analysing it. Once I had all this
data about the players and their weights, the next step in my method was to analysis
the matches played to get the required statistics, starting 8 in the scrum and the
scrummaging statistics of the match. Once I have all the data I need I will compare
both of these factors against those of the matches I will figure out the averages of the
scrummaging success for each team in each of their games and their average pack
weights. The results I got from my research showed that the teams with the heavier
packs had the more successful scrummaging successful on average, over the course of
the game I studied. The results were what I was predicting, in terms of the heavier
pack having the greater successful in the scrums, although I was apprehensive about
the results as there are other factors which could contribute to a teams scrummaging
success, such as through technique. The results showed that there is a relationship
between the pack weights and the scrummaging success as well as correlation.

Introduction
My research project which I have spent the last several
weeks on, is to found out if there is a relationship
between pack weight and the ability to have a successful
scrum. I chose to study this as I, myself play as a forward
and I am aware that over the last 10 years of the sport,
the laws and regulations regarding the scrum have
changed to try and make it safer to the players involved.
So I wanted to know if the new regulations required
teams to rethink the way they scrummage, as 10 years
ago it was all about the big hit and having the weight to
push the opposition off the ball, but with the way the
sport has advanced and developed in recent years, is the
scrum still all about that big hit and having a weight
advance over the opposition.

Project Hypothesis
For my research project I have 2 hypotheses which I want
to find out. The first is to find out if the team with the
heavier pack is able to have a more successful scrums
during a game, and does this have an effect on them
winning the game. The second is to find out whether or
not the team with the constantly heavier pack is able to
maintain a successful scrum throughout the season. I am
going to do this by studying the individual games statistics
and then compare them to other games throughout the
season. I think the heavier teams will be able to win more
scrums, giving them a greater success percentage.
However, whether or not this will mean they are able to
win the match is a different discussion.

Method
For my method of the research project, my project is
primarily desk based research, as I am gathering all my
data from a secondary source. Once I have collected all of
the data I need, I will be looking at the starting pack for
the teams I am studying in certain games, combining the
players individual weights to calculate an overall pack
weight. Once I have the packs weight I will look at the
games statistics for the scrums, to see how many each
team had won and lost during the game. I will repeat this
process for all the teams I am studying, and then I will be
analysing the results to see if there is a relationship
between the pack weight and their ability to win the
scrums.

Data Collection
To collect all the required data I needed I gathered
it all from doing desk research as all the data to
secondary sourced. Once I have gathered it all from
the online sources and have collected and
organised the data in a nominal classification, as I
have categorised the players into their teams, and
then again by their position. To get all the players
information I had to go into each teams individual
website and search each players profiles. The only
other data I need to collect is the game statistics
which I was able to gather from a single website.

Data Analysis
For my research project the data collection and analysis technique I
have used is by doing desk research, the data I have collected is
quantitative data and is of a secondary source, which I am using to
back up my research Hypothesis. I will be analysing the data I have
gathered by looking at the starting pack of the teams and by
combining the players individual weights to calculate an overall pack
weight. Once I have the packs weight I will look at the games statistics
for the scrums, to see how many each team had won and lost during
the game. I will repeat this process for all the teams I am studying, and
then I will be analysing the results to see if there is a relationship
between the pack weight and their ability to win the scrums, so this is
also a comparative study. I have collected and organised the data in a
nominal classification, as I have categorised the players into their
teams, and then again by their position.

Results
The results I have gathered show that there is a correlation
between the average pack weight and the average success
rate of the scrums. From this I can then determine that there
is a relationship the pack weight and their ability to win the
scrums. However there were 2 teams who had the same
matching highest scrummaging success percentage. One of
these teams, London Welsh, who have the average highest
pack weight and also have the highest average scrummaging
success, having a correlation of 0, however they have still yet
to win a game on the premier league this season. The team
which had the lowest average pack weight, Saints, also had
the lowest average scrummaging success rate, correlation of
0, however they have had much better results than Welsh,
which means that my hypothesis is partly correct.

Discussion
The results I got I was expecting as the teams which do
have the heavier pack are able to have a better
scrummaging success rate, however as I was expecting
the players don’t have the cardiovascular endurance, and
the team struggle in other parts of the game, such as in
open play, getting to the break downs. However the only
part of the game which I was analysing is the scrums. The
team which has the lowest average pack weight, is also
the team which is currently top of the Aviva premiership,
which means that though they have a smaller pack they
are able to get an advantage in other parts of the game.

Conclusion
My aim of the project was ‘To see if there is a relationship
between the weight of a scrum and the ability to have a
successful scrum.’
From the results I have gathered I can see that there is a
relationship between the weight of the scrum and the ability
to have a successful scrum, as I wanted to find out in the aim.
One of my hypotheses which was to see if the team with the
pack was able to maintain a successful scrum throughout the
session. The other which is to see if the pack with the heavier
weight was able to have a more successful scrum rate during a
game and whether or not they can turn that into a win. From
the statistics I have gathered the teams with the heavier pack
have not been able to turn the a successful scrum rate and
heavier pack into a win, this could be down to a number of
different factors, such as fitness.

Review (1/3)
I feel that the conclusions from my project met
my project aim of ‘To see if there is a
relationship between the weight of a scrum and
the ability to have a successful scrum’. In my
study in found that London Welsh on average
have the heaviest pack, and from the games I
analyzed they have the better scrummaging
success. Although they couldn’t turn this
advantage they have to winning advantage.

Review (2/3)
The strengths of my research project, I feel
would have to be the data collection and the
way I categorised the qualitative, secondary
data (see Appendix 1-3). This data was easily
accessible and to find. This meant it didn’t take
long to find and gather all of my required data
and meant I could focus on other parts of my
project.

Review (3/3)
My area for improvement would be the literacy
review, as in my opinion I struggled with this as I
found it difficult to find appropriate abstracts
which share a common Population, Measure
and Variable to mine. The ones I did found and
use I feel are useable however I would of
preferred better ones which share more in
common with my research project aim.

Future Recommendations (1/5)
If I was to do my project again, I would also have
looked at the forwards bench to see how those
players influence the game and whether or not
they have a impact on the set pieces (scrums.)
which would then give me more data to
analysis.
P4: Produce / P5: Describe / M3: Explain / D2: Justify

If I was to run my research project again, one
recommendation that I would make would be
see if there was another why to analysis the data
I have collected and then see there is another
why in which I could present it, possibly
presenting it in a number of graphs and tables
and then do a comparative study.

Another recommended improvement for my
research project would be, as well as studying all
12 teams within the selected league, I would do
more game analysis of the teams, looking at all
rounds of fixtures for the teams. This would
mean I would have a lot more data to
categories, chart and correlate.

Another thing I could of done if I wanted to be
more specific would be to focus on a single team
from the premiership and analysis all their
games, from all competitions. I would then go
into detail analysing the games, and stating how
squad selection would have been different for
certain competitions and fixtures due to players
being away on international duty or injury.

Another recommendation I could do if I was to
do this research project again would be that I
could do a comparison between the pack
weights of teams in different countries, to see if
there a difference between the playing styles
and the general play of the players. I would do
this by studying teams in both the southern and
northern hemisphere, as it is generally
suspected that northern hemisphere teams are
more physical up front.
