I believe you meant to ask: What distinguishes a random sample from a non random sample? A random sample means the selection or sampling from the population is by chance. Looking at the data, one might not be able to tell if the sample is random or selective. Consider a marketing survey which is included everytime you buy an item online. Random or non-random? It is a survey of recent customers, and probably a pretty good one. But it is not a random selection of all customers who have made purchases with clients.
How would you thoroughly demonstrate that a particular organism is the cause of a disease?
You're not meant to have foreign organisms inside your body (excluding the gut which technically isn't inside your body). So if you're sick and the organism can be isolated and cultured from a sample you gave from the area that is affected (eg a sputum sample if you have a chest infection, a blood sample if you have septacaemia), it has to be the cause of the disease. A control sample is always given to exlude the possibility of contamintation.
