Lab material exam 3 Flashcards
(12 cards)
Errors are measured as
Space
Time
Frequency
What is spatial error
Example
Measures the distance as short or long
Shooting a basketball long or short
What is temporal error
Example
Measure early or late
Swinging the bat early or late
What does linear positioning test
How is error involved
Proprioception
Can be short or long
Can be too fast or too slow
To overshoot a target means
Is it positive or negative
Projectile or object goes beyond the target
Positive
To undershoot a target means
Is it positive or negative
Projectile or object falls short of the target
Negative
What is algebraic error
The raw data extracted from an instrument
What is constant error
What is it derived from
Measures the individuals response bias
The mean of the algebraic error scores
What is the variable error
What is it derived from
When should it be reported
A measure of an individuals variability around the constant error score
Derived from calculating the standard deviation of the algebraic error scores
Should be reported when constant error is reported
What is absolute error
Calculated by removing the signs of the trial scores and then computing the mean
What is counterbalancing
To check to see if the order with which we do things affects performance outcomes
When is counterbalancing used
Why is it important to control it
When you have multiple conditions
Due to fatigue, boredom, learning and maturation on the outcome
