Question

ankylosing spondylitis is a chronic form of arthritis. a study was conducted to determine whether daily stretching of the hip tissues would improve mobility. the data are found in hips. the flexion angle of the hip before the study is a predictor and the flexion angle after the study is the response. plot the data using different plotting symbols for the treatment and the control status, and give a summary of initial findings from these plots

Answer 1

Ankylosing spondylitis is a type of arthritis where a study examining the impact of daily stretching on hip mobility would compare the hip flexion angle before and after the experiment in treatment and control groups.

Step-by-step explanation:

Ankylosing spondylitis is a chronic form of arthritis characterized by inflammation and leading to reduced mobility of the joints. A study focusing on whether daily stretching of the hip tissues could improve mobility would involve measuring the hip flexion angle before and after the intervention. When plotting the data, it is important to distinguish between treatment and control groups to see if stretching has a significant effect on hip mobility.

Upon reviewing such plots, initial findings might reveal trends or differences in mobility improvement between treated participants versus controls. The conclusion about the effectiveness of daily stretching in improving the flexion angle could thereafter be made by comparing these groups.
