Identify the training level and sport for the group that has the highest mean score on the standing broad jump fitness test.

Calculate the difference of mean standing broad jump fitness test score between moderate and high training levels for the group stated in 1(a)(i).

Using the data, deduce the effect of high level of participation in sport on performance in the standing broad jump test.

A two-tailed, unpaired t-test was conducted on the data. The calculations yielded the following results:

• comparing low and moderate training level yielded p > 0.05
• comparing moderate and high training level yielded p < 0.05
• comparing low and high training level yielded p < 0.01.

Comment on the meaning of the results from the t-test.

State an alternative test (other than standing broad jump) for measuring leg power.

Outline the procedure for measuring leg power in the test stated in 1(b)(i).

gymnasts with high training level ✔

Both gymnast and high required for [1] mark.

160−140 ✔

=20 «cm» ✔

Accept the subtraction in a different order.

Accept correct calculation if (a)(i) is incorrect.

children who regularly participate in sport perform better on standing broad jump ✔

gymnasts perform better than children from other sports across all participation levels ✔

A high level/>5hr per week of training appeared to have a significant effect on standing broad jump performance in every sport when compared to the other 2 groups/ the greater the training the greater the effect✔

Accept other reasonable hypothesis.

low to moderate training level group did not show «statistically» significant results ✔

moderate and high training level group did show «statistically» significant results/ showed they were significantly different to 95 % ✔

low and high training level group did show «extremely statistically» significant results/ showed they were significantly different to 99 % ✔

Accept response if “significant” is mentioned once but implied in the rest of the answers. Eg the low to moderate training level did not show significant results but the moderate and high training level group and the low and high training level group did.

vertical jump/Sargent test ✔

Accept valid tests eg Wingate, Margaria-Kalamen.

place a vertical marker from a standing position
OR
create a “baseline” measurement ✔

perform a two-foot take-off ✔

bending knees/swinging the arms for the take-off ✔

place a vertical marker at the apex of the jump ✔

power is measured as the distance from standing position marker to marker at the apex of the jump✔

Despite current research award [1] mark for warm-up.

Accept protocols for alternate valid test from (b)(i).

The data questions (a)(i) and (a)(ii) were completed very well overall with no issues.

The data questions (a)(i) and (a)(ii) were completed very well overall with no issues.

Candidates struggled to get full marks with (a)(iii) – the command term required a slightly different way of thinking about the data and is an area that they can work on.

a(iv) was a new type of statistical question which had mixed results. Some students had the explanations the wrong way around such that p>0.05 was significantly different while the others were not. With these types of questions, it is important for candidates to consider what the data is showing and whether their comment on the significance of the difference matches what is shown.

(b)(i) was generally picked up well. 

The outlining the procedure of the test; 1bii, was not always clear.
