Question
Transcribed Image Text:Researchers were interested in comparing the depression levels for Australian adults from four different age groups (18 to 29; 30 to 39; 40 to 49; and 50 to 59). They
suggested that depression levels for 18 to 29 year olds would be lower compared to 30 to 39 year olds. They also expected this difference in depression levels to be greater
for females than for males. Note: depression levels were measured on a metric scale, with higher values indicating higher levels of depression.
Which of the options below best describes the presented research design?
