These significance tests we're assuming that the
The assumed proportion, remember when we're doing Of how she gets this, she's really trying to say well how many standard deviations above We do this in other videos, but just as a reminder And then she calculates the test statistic for these results was Z isĪpproximately equal to 1.83. Her sample proportion which is 40 out of 120 and this is going to be equal to one-third, which is approximately equal to 0.33. The population of her city, she took a sample, her sample size is 120. She found that 40 of 120 people sampled could speak more than one language. Proportion of people in her city that can speak more than one language. Is it's actually greater than 26%, where P represents the She was curious if thisįigure was higher in her city, so she tested her null hypothesis that the proportion in her city is the same as all Americans, 26%. The Journal of Strength & Conditioning Research. Reliability and Validity of the T-Test as a Measure of Agility, Leg Power, and Leg Speed in College-Aged Men and Women. PAUOLE KAINOA MADOLE, KENT GARHAMMER, JOHN LACOURSE, MICHAEL ROZENEK, RALPH.Reliability: the type of surface that is used should be consistent to ensure good test-retest reliabilityĪdvantages: This is a simple agility test to perform, requiring limited equipment and space.ĭisadvantages: Only one person can perform the test For safety, a spotter should be positioned a few meters behind cone A to catch players in case they fall while running backward through the finish. The table below shows some scores for adult team sport athletes.Ĭomments: Ensure that the subjects face forwards when shuffling and do not cross the feet over one another. Take the best time of three successful trials to the nearest 0.1 seconds.
#Standard normal table t test trial#
Scoring: The trial will not be counted if the subject crosses one foot in front of the other while shuffling, fails to touch the base of the cones, or fails to face forward throughout the test.
The stopwatch is stopped as they pass cone A. They then shuffle back to cone B touching with the left hand, and run backwards to cone A. Then shuffling sideways to the right to cone DĪnd touching the base with the right hand. They then turn left and shuffle sideways to cone C, and also touches its base, this time with their left hand. On the command of the timer, the subject sprints to cone B and touches the base of the cone with their right hand.
Test setup: Set out four cones as illustrated in the diagram above (5 yards = 4.57 m, 10 yards = 9.14 m). Prepare forms and record basic information such as age, height, body weight, gender, test conditions. Perform screening of health risks and obtain informed consent. Pre-test: Explain the test procedures to the subject. Purpose: the T-Test is a test of agility for athletes, and includes forward, lateral, and backwards running.Įquipment required: tape measure, marking cones, stopwatch, timing gates (optional)
