Purpose of Experiment

The Stick, Stock and Modified Sideward Leap tests determines the individual’s ability to stand in an awkward stance. There is no limit on time and the time that is recorded from each student will be combined, as the mean, to say this is the most average balance the students have in a given class. Being able to balance is a common task that is not associated with performance, but primarily three tests that is a common balance for everyday use. The students will be test over the common balances of everyday, to see where the students stand, in a general ability to do so. There is no right or wrong during the test. The student will start when the timer starts, and end when the student fails to proceed for the given position. All data will be recorded, and conclusions will be made of excellent or poor balance, when all the numbers are categorized in the right areas of the test. Once the whole class has been administered the test, the mean will be tallied up, to show how the whole class did. Once that is found, the mean will be compared to others that have had the same test. The results will be compared with the Stork test of two groups, students vs. young gymnasts.

Hypothesis

The Modified Sideward Leap is the hardest test and will have the longest time than compared to the Stick test, having to balance just on one foot. The difficulty of the test will determine the time the student will get. After seeing the final scores, a time can be closely predicted for the next time a student is administered this test. With this prediction, the scores should stay in the same area for each individual as they are given the test

Methodology

Stork

            The stork test is given to all students. Before the test can be administered, there must be a demonstration. The demonstration is standing in a ready stance, and on “go”, the student will bend the knees slightly, not exceeding the 90 degree angle from the knee to the hip, and will place the dominant leg over the non-dominant leg. After this happens, the student will then be asked to raise on the ball of their foot, with the foot that is left on the ground. Once the student is able to raise on the ball of their foot, the time will start with the hands on their hips. The student must be able to hold this position as long as possible without the slightest movement. Any change in position will result in a stopped time. The time will be recorded. The student must do at least three trials of the stork. There is no apparatus being used in this test and there are 17 students involved with this experiment.

Stick test

            The Stick test will use all of the 17 students in the class will be expected of the students to do at least 3 trials of this test. The apparatus that was used was hockey sticks and the student standing on the hockey stick will be using only one foot. When the person administering the test says “go”, the student will step up on the stick with the ball of their foot, and will hold the upward position as long as possible. Once the student steps off the stick or loses its balance, will have time stopped and recorded.  

Modified Sideward Leap

            There will be 17 students involved and the will do at least three trials or more for this experiment.  The student will begin on an x with their left foot, with the right side towards spot A. The student will be asked to leap towards their right side and land on their right foot on spot A. Once the student lands, they will stay on the one leg and lean forward to push a cork off spot B. After the cork is moved on off spot B, the student must hold that position for 5 seconds. After then student goes to the right side, completely, they must do the left side as well.

Interpretation *Graph above represents numbers in seconds achieved by students and the mean for each divided experiment (Stick test, Stork, Modified) tests.

Interpretation *Bar Graph above gives a visual of how similar the classmates did against each other in time. Notice the modified leap test is more significantly constant thank oppose to the others that vary greatly. Stork test varies the most.

 

            The references were taken from an article that had young men and women gymnasts do the stork experiment.  From the results, the gymnasts from the article have better balance than the students in the class that was test.
