IB Sports, exercise and health science (SEHS) SL Internal Assessment Example

How does reaction time in dominant vs. non-dominant hand differ, measured by using the ball drop reaction time test (in seconds), in school’s U14 Volleyball girl’s team (taking into consideration that the error of uncertainty due to human error +- 0.05s)?SL

IB Grade: 6

Criteria A: Research design

5/6

Criteria StrandsPro

A.1Research question context

Excellent

A.2Methodological considerations

Good

A.3Reproducibility of methodology

Moderate

Criteria Feedback

The student posed a focused, measurable question in a clear volleyball context.
The student explained why the investigation matters by linking it to handedness and sport-specific performance.
The student included several relevant methodological considerations such as repeated measures, practice trials, ethics, and timing the study carefully within training.

The student did not fully explain how dominant hand was determined.
Some important controls, especially trial order and hand order, were not clearly handled.
The method is detailed enough to follow in places, but not yet fully robust or unambiguous for exact reproduction.

Criteria B: Data analysis

B.1Communication of data

Moderate

B.2Consideration of uncertainties

Moderate

B.3Processing quality

Poor

Criteria Feedback

The student presents the main processed data clearly using tables and a graph with error bars.
The student includes standard deviations and acknowledges variation, uncertainty, and possible anomalous results.
The student attempts relevant statistical processing by using a paired t-test to compare the same participants across both conditions.

The communication of the processed data is generally clear but not always precise, especially in labelling and in describing how summary values were formed.
The student's handling of uncertainty is only partly successful because the manual stopwatch error is recognized but not properly quantified or built into the analysis.
Some processing steps contain significant weaknesses, including an unclear summary method and an incorrect effect-size result.
