A comparison of response time across genders - the "Ruler drop test"
The materials required for the experiment are as follows:
- 20 boys and 20 girls aged 15
- a ruler
- writing materials
1. For this experiment, the independent variable is the participants’ gender. The dependent variable is the participants’ response time when it comes to catching a ruler that has been dropped. Measure how far the ruler falls before it is caught by the participants. The constants (control variables) are to be the weight of the ruler and the participants’ age.
2. The first participant is to position his/her thumb and his/her index finger in a horizontal “V” shape.
3. Hold the ruler between the participant’s 2 fingers. The tester should hold the tip of the ruler and the base or the “0 cm mark” should be nearer to the participant than the tester. The participant’s fingers should not touch the ruler. Tell the participant that the tester will drop the ruler, and that he/she is to catch it using his/her 2 fingers.
4. Release the ruler such that it falls vertically. The participant is to catch the ruler using his/her thumb and index fingers. Record the distance the ruler falls before it is caught.
5. Repeat the test 5 times with each participant. For each participant, calculate the average distance the ruler falls before he/she catches it. Record this in the table below.
6. Repeat procedures 2, 3, 4 and 5 with the rest of the participants.
