Domain 5 Analysis and Data Usage

Question 1

True or False, Survival is the cumulative proportion of a population who are alive over time.

Answer 1

True

Question 2

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

Answer 2

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.

Question 3

Population-based registries receive cancer data from:

Answer 3

Hospitals and independent pathology labs

Question 4

The study of the distribution and determinants of disease in the human population is called:

Answer 4

Epidemiology

Question 5

A cross sectional study:

Answer 5

Determines prevalence

Question 6

Sensitivity is best defined as:

Answer 6

the ability of a test to give a positive finding when the person tested truly has the condition

Question 7

True or False, The null hypothesis states that the observed difference is simply the result of random variation in data.

Answer 7

True

Question 8

Tables in a report should:

Answer 8

Have as much white space as possible surrounding the rows and cells.

Question 9

In comparing the risk of diagnosis of cancer in all males for populations with different age distributions, the best measure is:

Answer 9

Age-adjusted incidence rate

Question 10

True or False, Incidence is a rate which represents the number of new cases in a populations over a period of time.

Answer 10

True

Question 11

A study that begins collecting cases at a given starting point and stops collecting cases at a specific point in the future is called:

Answer 11

Prospective

Question 12

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.

Answer 12

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.

Question 13

Of the methods for calculating both incidence and survival rates used by central cancer registries, a “relative survival rate” is…..

Answer 13

Cancer cases expected to die from cancer.

Question 14

The way values for a variable are distributed is called the:

Answer 14

Frequency distribution.

Question 15

The p value is the:

Answer 15

Probability that a difference as large as that observed would occur by chance alone

Question 16

Population based central cancer registry data……..

Answer 16

Contains all cases in a defined geographic region.

Question 17

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

Answer 17

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.

Question 18

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

Answer 18

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.

Question 19

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

Answer 19

Record linkage

Question 20

Measures of central tendency are:

Answer 20

Mode, median, and mean
