Describing our samples - rugby player weights by Cushla Thomson

In my sample the median weight of backs is 94 kg, this is just 6.5kg less than the median weight of forwards which is 100.5 kg. I would expect to see this in my population as the role of forwards in rugby requires them to be heavier to take out the opposition, for example in scrums. The backs tend to be lighter as they depend on their speed to run around the defenders.

In my sample, the median weight for the backs is 92, which is 18.5 kgs less than the median weight for the forwards. This is what I predicted, because forwards need to be big units to push in the scrum and make short runs, while backs need to be lighter and faster so that they can outrun the opposition. The middle 50% of the forwards are located between 104.8 kgs and 117 kgs whereas the middle 50% of the backs is located between 88 and 95.5 kgs. Тhere is no overlap between the two interquartile ranges, which reinforces these observations and all but confirms the points made about position roles. An example of a big prop is Chris Eves, pictured below.

In my sample, the median weight of forwards (110.5kg) is 18.5kg lighter than the median weight of forwards (110.5kg). This does not surprise me at all because forwards have roles on the pitch the require more mass, such as scrums, malls, ruck

In my sample, the median weight of forwards (110.5kg) is 18.5kg heavier than the median weight of backs (92kg). In my sample, the middle 50% of forwards weights are between 104.5kg and 117kg, whereas the middle 50% of backs weights are between 88kg and 96kg. I would expect to see the median weight of forwards heavier than the median weight of backs because the forwards require a lot more strength to scrummage, lift players in lineouts, and tackle, whereas the backs main task are running with the ball and kicking.
Spread
In my sample, the interquartile range for forwards is 12.5kg, which is greater than the interquartile range for backs, which is 8kg. This means that there is more spread in the weights of the forwards than there is in the weights of the backs. I would expect to see this variation as there are a number of different positions in the forward pack which have slightly different roles, such as props and loose forwards.
Shape
The forwards weights appear to be skewed to the right whereas the backs weight seems reasonably symmetrical.

In my sample, the median weight (kg) for the backs is 92kg, this is 18.5kg less than the median weight (kg) for the forwards (110.5kg). This does not suprise me because larger players are best suited for forwards and will be more effective in scums and to make hard and heavy tackles. On the otherhand back players are best nimble and light to evade the heavier players and to make fast and agile runs up the pitch in order to score trys.

In my sample, the median weight of forwards (110.5kg) is 18.5kg heavier than the median weight of backs (92kg). This is what I would predict because the forwards are depended on to push the scrum and make short runs and to do this effectively they need to be heavier than back players who are more nimble.

In my sample the median weight of forwards is 110.5 kg which is 18.5 kg heavier than the median weight of backs ( 92 kg). This is what I would expect as forwards need to be stronger in order to ruck the ball and make short dashes. Forwards need to be quicker and therefore lighter.

Центр
В моем образце средний вес для форвардов (110,5 кг) составляет 18,5 кг тяжелее среднего веса спин (92 кг). Это то, чего я ожидал из-за роли форварда, потому что они участвуют в схватках, поэтому их добавленный вес помогает им быть успешными в схватке.

In my sample, the median weight for the forwards (110.5 kg) is 18.5 kg heavier than the median weight of the backs (92 kg). This is what I expected due to the role of the forward, in that they are involved in scrums, so their added weight helps them to be successful in scrummage.

In my sample there is forward who weighs a lot more than the median weight for a forward (110.5), weighing in at 137 Kgs. This is 8kg higher than the next heaviest player who weighs 129kg.

In my sample, the median weight of the forwards is 110.5 kgs is heavier than the median weight of backs. This is what I expected to be shown in the sample. This is because the forwards have to be in scrum to push it forward and go into rucks. The backs are expected to be lighter in order to makes runs and plays. We see there is more variability in the
