To ensure that the data is valid, which of the following actions is most essential during the preparation stage?

In the steps and guidelines for performance analysis, a researcher performs a test where the same analyst codes the same basketball game footage on two separate occasions one week apart. This procedure is used to establish which of the following?

When developing an observational system for soccer performance analysis, which of the following represents the most objective operational definition for a 'successful tackle'?

A performance analyst uses the following formula to calculate 'Scoring Efficiency Index' (SEI):
\( SEI = \frac{\text{Goals Scored}}{\text{Total Attempts} - \text{Blocked Shots}} \)

Player A: 50 Total Attempts, 15 Goals, 10 Blocked Shots
Player B: 40 Total Attempts, 12 Goals, 4 Blocked Shots

Based on the calculation, which player is more efficient and what is their SEI score?

During the preparation stage of a performance analysis project, why is it essential to conduct a pilot study with a small sample of match footage?

Identify one advantage of using systematic observation over casual observation in the analysis of sports performance.

A performance analyst observes that a specific electronic timing system consistently records a 0.02-second delay for every runner. Discuss whether this system is reliable and objective for calculating personal bests.
