Question
Could someone confirm that my two-way table is correct, and explain the 'signal' and 'noise'?
Given the following summary of evidence from a study, construct a two-way table with columns for Treatments and rows for outcomes to display the data. "In a randomized clinical trial to determine the most effective timing of administration of chemotherapeutic drugs to lung cancer patients, 16 patients were given four drugs simultaneously and 11 patients were given the same drugs sequentially. Objective response to the treatment (defined as shrinkage of the tumor by at least 50%) was observed in 11 of the patients treated simultaneously and in 3 of the patients treated sequentially." a) Construct your table below, with suitable labelling of all rows and columns. b) Using the data from this clinical trial, identify the 'signal' involved in this study and discuss how the given data address this signal {without coming to a statistical conclusion}. Then identify the "noise" involved in this study and discuss how the given data address the noise. Recall, in your answer, the concepts of variation within treatments or groups and variation between treatments or groups.Explanation / Answer
Yes your two way table is correct.
Signal is anything that investigator is trying to measure. Here investigator is trying to measure true the most effective timing of administration of chemotheroputic drugs to lungs cancer patients. In simultaneous given of four drugs the signal is 11 and noise is 5 and in sequential given of four drugs the signal is 3 and noise is 8 Therefore simultaneous given of four drugs results good as compare to sequential given of four drugs.
