A Single Case Evaluation of The Link Between Stress During and after Yoga Practice

This is a description of a single case evaluation examining a relationship between stress during a test before practicing yoga and after practicing yoga. A single case evaluation is defined as a time series design used to evaluate the impact of an intervention or a policy change on individual cases or systems (Rubin & Babbie, 2014).

Stress during a test will be lower if the student participates in yoga on a daily basis. The observable indicators for my independent variable in the single case evaluation would be negative. It is negative because there is a significant problem present.

In considering operational definitions some students not that practitioners might rely on the client’s complaint that a particular problem requires attention. Practitioners are using an operational definition that is they are persuaded to work on a problem on the basis of their observation of the extent of the client’s expressed difficulty or dissatisfaction with the problem. Thus, they could take prepared measures simply by having the clients indicate daily on a belief scale the degree of difficulty they felt they experienced with the problem that day (Rubin & Babbie, 2014)

For the case of my single case evaluation (stress levels during a test before and after yoga), the stress test could be used to test the level of stress in a person. The test would be done before the academic test. I would then participate in yoga and see if my stress levels go down before taking another academic test.

When considering alternative sources of data (available records, interviews, self- report scales, or direct behavioral observation) (Rubin & Babbie, 2014)

Sources of data for my particular case would be the stress test or even direct behavioral observation in direct behavioral observation I would participate in self- monitoring where I would observe how I am feeling after participating in yoga before my test.

Triangulation is the use of two or three indicators. It refers to situations in which researcher are confronted with a multiplicity of imperfect measurement options, each having advantages and disadvantages. To maximize the chances that the hypothesized variation in the dependent variable will be detected, the researcher triangulates measures more than one measurement option is used (Rubin & Babbie, 2014)

In the case of my evaluation of stress during a test before doing yoga and after doing yoga the evaluators could also look at how hard the class is and also see if there is other factors stressing the student out that caused the high stress levels before the test.

Frequency distribution is description of the number of time the various attributes of a variable are observed in a sample. Magnitude is the size or extent of something. Duration is the time in which something occurs.

For my case I could use many of these terms. The one term that can be applied the most is duration. I could look at how long before the test does the stress occur and even examine how long the stress last.

Baselines are control phases of repeated measures taken before an intervention is introduced. Ideally should be extended until a stable trend in the data is evident (Rubin & Babbie, 2014).

Five days leading up to the test the student had high levels of stress. There was a steady trend of stress. After the stress level test (the cardiac test) the levels of stress decreased.

The test that I would be using to test the level of stress would be the cardiac test. The cardiac test consist of someone running on a treadmill as the level of stress is being calculated on a monitor.

When looking up the definition of intervention variable the book referred me to mediating variable. Mediating variable is the mechanism by which am independent affected a dependent variable (Rubin & Babbie, 2014).

When it came to the intervention variable (yoga) my stress level dropped from a 4 to a 5. It stayed consistent on a 4 after my intervention was added.

The stress level before and after yoga was very similar. There was some changes, but not a change that was that noticeable. My intervention of yoga was not affective for the level of stress while taking a test.

There really was no change in my numbers. The stress level did not decrease that much after the student participating in yoga.
