Section 2 ISA Revision

Question 1 - Do your results support your hypothesis?
-Yes //-Pattern supports it because as time interval decreases the time until muscle fatigue occurs also decreases // -Example (5s-994s and 1s-152s)
1 of 11
Question 2 - Did you get any anomalous results?
-Yes // -Not all results fitted the pattern // -Much higher than other results produced for that time interval // -Example (882s much higher than 563s and 549s)
2 of 11
Question 3 - Describe in detail how you could use repeat readings to obtain more accurate results.
-Calculate a mean // -Give formula (sum of all results divided by number of results) // -Don't include anomalies in the calculation
3 of 11
Question 4 - What was the independent variable?
-The interval time between lifts of a 1kg bag using the bicep muscle
4 of 11
Question 5 - What was the range of the independent variable?
-1-5 seconds
5 of 11
Question 6 - Was this a suitable range?
-Yes // -Talk about the difference between the highest and lowest results
6 of 11
Question 7 - Why might someone get different results than you did?
-Same resting time? // -Different subjects? // -Any other differences?
7 of 11
Question 8 - Sketch Graph
-Will the line go up or down? // - Is the data going up or down with even intervals?
8 of 11
Question 8 - Even intervals
-If there are even intervals between the results of the dependent variable : it will be a straight line
9 of 11
Question 8 - Uneven Intervals
// -If they are uneven: the line will be a curve // -If the interval widths are getting bigger : the line will be steeper // -if they are getting smaller the line will be shallower
10 of 11
Question 9 - How could results be useful in the context you have researched?
-Used to show if altitude training affects the rate of respiration // - Can determine if they are using performance enhancing drugs
