Reliability and validity are important factors; they are key factors for having a good test. Reliability is when your test is consistent, whereas validity is the accuracy of your test. You can have a reliable test, yet not valid, but you cannot have a valid test without it being reliable. Here is an example of how reliability and validity work together. Let’s say your scale is 5lbs off, if you weigh yourself it will consistently weigh you 5 lbs off, this is reliability. Validity is your test measuring what it was meant to measure. This means the scale is not valid because it is measuring 5lbs off; it is inaccurate towards your weight. Therefore our scale was reliable, but not valid.
Method Numbers of participants in this study are 109, 76 of them are female, while the other 33 are male. The mean for all of our participant’s age is 19.48, while our SD is 1.119. There were not very large gaps in age for this study. So the oldest participant …show more content…
The type of validity used for this test was construct validity. Construct validity is a test based on some kind of underlining psychological construct or idea.
How would we assess that for this scale? For this scale we were using 10 items to measure whether or not some had low or high self-esteem. Some of the items on the test measured high self-esteem, while some of the items were related to low self-esteem. We could propose that people with depression have lower levels of self-esteem than people with high self-esteem.
After the participants were to take this test, we could evaluate the scores and see if our lower scores correlate with depression. We would also look at our high scores to ensure that they are not correlated with depression. If the correlation is high between low scores and depression etc. and the correlation is low between higher scores and depression then the items we chose for our test were on track with measuring
