Question 161

Fiona conducted an investigation to see whether cognitive-behavioural therapy (CBT) delivered via a smartphone app was as effective as CBT delivered via group workshops. Interested participants signed up after seeing a poster in an outpatient clinic.

Her participants were assigned to one of two conditions:

  • Condition A: CBT was delivered via a smartphone app.
  • Condition B: CBT was delivered via group workshops.

After six weeks of treatment, Fiona asked each participant to classify their anxiety levels as: 'Decreased', 'No Change', or 'Increased'.

State one reason why Fiona used a chi-squared test to analyse her data.
