is less responsive to treatment.
Yes. In Schizoaffective Disorder, criterion A is met for schizophrenia (delusions and hallucinations), but there is the ability to generate affect (show emotion) which confers are an improved prognosis and treatment course - as compared to schizophrenia proper.
Yes. Schizophrenia is partly genetic, meaning that if you have a relative with schizophrenia you are likely to also have schizophrenia. About 1/10 of people with a relative with schizophrenia develop schizophrenia, compared to 1/100 people without a relative with schizophrenia.
A randomized controlled trial (RCT) is typically used to evaluate the effectiveness of a new medication in reducing symptoms of schizophrenia. Participants are randomly assigned to either the new medication or a placebo, and their progress is closely monitored and compared to determine if the medication is more effective than standard treatments.
Population statistics on the heredity of schizophrenia estimate that a child with one diagnosed parent has about a 10% genetic risk of developing the disease themselves (this is compared to a 1% risk in the general population). The risk goes up significantly if both parents (60%), a grandparent, or other close relatives also have schizophrenia.
no however there is a disproportionate number of homicides by schizophrics compared to the number of those actually diagnosed
it is called Archiovery
The group that is the standard against which results are compared is called the control group. This group receives no treatment or a standard treatment, allowing researchers to compare the effects of the treatment being tested.

biometric
Yes it can be as for example the density population can be compared using statistics.
Schizophrenia is partly genetic- one out of ten people who have at least one schizophrenic relative also have schizophrenia (compared to one out of one hundred people in general). About one out of two people whose identical twins have schizophrenia also have schizophrenia. However, schizophrenia is not completely genetic. If schizophrenia was completely genetic, everyone who had an identical twin with schizophrenia would also have schizophrenia. This is not the case. Like I said before, about 50% of people whose identical twins have schizophrenia also have schizophrenia. There are environmental as well as genetic factors to schizophrenia.
An investigation in which a group that receives some experimental treatment is compared to a group that does not receive the experimental treatment can be called a placebo-controlled study or a comparative experiment, both of which are types of clinical studies. The group receiving the experimental treatment is called the treatment group, and the group that is not receiving the experimental treatment is called the control group.
