Question

Scenario 1: A study was conducted to investigate the effect of an intervention on osteoporosis in women. The intervention consisted of a three month educational program including informational speeches, discussions, question and answer periods, and poster displays. The bone mineral density was recorded at the lumbar spine before the intervention, at the d of the educational program, and six months after the completion of the intervention. Researchers were interested in whether there was a difference in bone mineral density over the time period of the study. Identif'y the independent and dependent variables for this study. 2 pts) Independent: Bone Mineral Density (in) time period. Dependent: Effect of intervention on osteoporosis. Is this an example of a One Way ANOVA design, a Repeated Measures ANOVA, or a Two Way ANOVA design? Justify your response. (2 pts.) ER F8 F7 F5

Explanation / Answer

here bone mineral density time period is independent variable and you are right.

The two main variables in an experiment are theindependent and dependent variable. Anindependent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.

this is example of One way anova ,

The one-way analysis of variance (ANOVA) is used to determine whether there are any statistically significant differences between the means of two or more independent (unrelated) groups (although its tend to only see it used when there are a minimum of three, rather than two groups).
