Use the belоw tаble tо аnswer questiоns 33 аnd 34. This is a table from a trial of a clinical intervention for patients living with multiple chronic conditions (Salisbury 2018). Assume you are using the standard value for alpha. Based on the table, the difference in means between the intervention and control groups for the outcome variable "Mean HADS Depression score" were:

Measures of knowledge were taken before and after the education for both groups. A survey was used to measure the knowledge that was scored 0-100 (higher score indicating greater knowledge). What type of analysis could be used to see if the level of knowledge for ONLY the intervention group participants changed between the two time points? You might do this to see if the intervention improved their knowledge.
