Q

A primary objective of conducting epidemiologic cancer surveys is to develop clues about the:

A

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.

them.

Q

Population based central cancer registry data……..

A

Contains all cases in a defined geographic region.

17
Q

Which of the following data sources is used by researchers to obtain income and literacy information that can be used to help define
and address the cancer burden in the region?
-Behavioral Risk Factor Surveillance System (BRFSS) data
-Central registry data
-Vital records mortality data
-None of the above

A

None of the above
United States census data provides information regarding population income and literacy that can be used to help define and
address the cancer burden in the region.
(BRFSS) provides data on items such as obesity, exercise, smoking and not being
screened.
Central registry provides data on incidence, stage and treatment. Vital records provide cancer mortality data.

18
Q

True or False, Three measures of variability are range, variance, and standard deviation.

A

True
Range is the difference between the highest value and the lowest value.
Variance is the average square of distance of observations from the mean.
Standard deviation is the square root of variance.

19
Q

A central registry has the ability to combine information from several sources. This ability is called:

A

Record linkage

20
Q

Measures of central tendency are:

A

Mode, median, and mean
