Statistical Analysis
In the scientific display of data, the function of error bars are to show this.
Variation or variability around the mean.
The variable that is expected to change located on the y-axis.
What is the dependent variable?
This type of test uses fitness tests and does not use specific indoor equipment.
This is useful when comparing the means and the spread of data between two or more samples.
What is standard deviation?
A variable that is intentionally changed to observe its effect located on the x-axis.
What is an independent variable?
This type of test uses specific equipment. An example is a VO2 max.
What is a laboratory test?
This is the standard deviation expressed as a percentage, allows us to compare 2 data sets that have different units, and is useful for representing the reliability of athletic events or performance tests.
What is the coefficient of variation?
The degree to which a measure would produce the same result from one occasion to another.
What is reliability?
This is needed before someone takes part in a physical test, so they will not put their health or life at risk.
What is a PAR-Q?
1. This % of scores will fall within 1 standard deviation.
2. This % of scores will fall within 2 standard deviations.
1. What is 68%?
2. What is 95%?
The variables you keep the same in an experiment.
What is the control variable?
A VO2max test or Bench test. It might be hard for those who are not use to doing a test like this.
What is a maximal test?
The t-test tells us this.
What is the difference between two sets of data is significant or just chance?
It measures what it claims to measure, obtained with a reduced system of error.
What is validity?
This test is good for children, elderly, or someone who is not fit because they are not aware of what they can handle or concerned of pushing it too hard.
What is a submaximal test?
