Domain 5 Analysis and Data Usage Flashcards
True or False, Survival is the cumulative proportion of a population who are alive over time.
True
A primary objective of conducting epidemiologic cancer surveys is to develop clues about the:
Etiology: the cause, set of causes, or manner of causation of a disease or condition.
Cancer is caused by changes (mutations) to the DNA within cells. The DNA inside a cell is packaged into a large number of
individual genes, each of which contains a set of instructions telling the cell what functions to perform, as well as how to grow and
divide.
Population-based registries receive cancer data from:
Hospitals and independent pathology labs
The study of the distribution and determinants of disease in the human population is called:
Epidemiology
A cross sectional study:
Determines prevalence
Sensitivity is best defined as:
the ability of a test to give a positive finding when the person tested truly has the condition
True or False, The null hypothesis states that the observed difference is simply the result of random variation in data.
True
Tables in a report should:
Have as much white space as possible surrounding the rows and cells.
In comparing the risk of diagnosis of cancer in all males for populations with different age distributions, the best measure is:
Age-adjusted incidence rate
True or False, Incidence is a rate which represents the number of new cases in a populations over a period of time.
True
A study that begins collecting cases at a given starting point and stops collecting cases at a specific point in the future is called:
Prospective
True or False, A ration is the total population divided into parts using a different unit of measurement over the same time and forming a fraction of
them.
False:
A ration is the total population divided into parts using the same unit of measurement over the same time and forming a fraction of
them.
Of the methods for calculating both incidence and survival rates used by central cancer registries, a “relative survival rate” is…..
Cancer cases expected to die from cancer.
The way values for a variable are distributed is called the:
Frequency distribution.
The p value is the:
Probability that a difference as large as that observed would occur by chance alone
