4 desired characteristics of statistical data

What are the values of centrality? (3)

What type of quantitative data is time, weight, and height

Counting numbers are what type of quantitative data?

Nominal scales are often used for what type of research

A census if different from a sample survey in what way?

True or False:

Ratio scales have true zeroes

True or False:

Interval scales have true zeroes

True or False

Temperature has a true zero

The average

True or False:

Mean data is symmetric

What are the values of variability?

Square of the standard deviation

True or False:

The larger the value of variance, the less variability there is

True or False

SK > 0 means that the data is skewed to the left and therefore negative and pulls the average down

True or False

SK < 0 means that the data is skewed to the right and therefore positive and pulls the average up

Referred to as higher kurtosis

Referred to as lower kurtosis

True or False:

All participants have a 0% chance of being selected in a probability sampling design

Every element has an equal chance of being selected in the sample

Population is divided into non-overlapping groups, strata

True or False

A cohort study that follows up on the health situation of patients is called a retrospective study

Participants of a cohort study are divided into what groups?

True or False

The case group in case-control study refers to the participants with the disease

What is an ecological fallacy

If your sample size is an odd number, how many medians are present?

How do you get the median of a population with an even number

Values which are relatively unusual or far from all other observed values

The difference between the highest and lowest value in a set of observations

Divides a set of observations into 100 equal parts

True or False

A score at the 1st percentile means that it is the highest score in the data

True or False

A skewness of zero means that the data is invalid

True or False

The 3rd quartile is also the 50th percentile

True or False

Deciles are observations divided into 10 equal parts

True or False

Quartiles are data divided into 25 equal parts

Referred to as the class with the most number of observations

A comparison of two numbers wherein the numerator is part of the denominator

Comparison of two numbers

Mortality rate defined as the total deaths (all causes) over the average population

True or False

Crude death rates are useful in comparing community health status even if their composition is different

Defined as the total deaths of a particular cause divided by the average population

Defined as the total deaths (all causes) in a particular age group divided by the average population

Defined as the total deaths (all causes) in a particular sex group divided by the average population

Defined as the total deaths of a particular cause divided by the number of all deaths of all causes

Defined as the total deaths of all causes in a particular age group divided by the number of all deaths of all causes

Defined as the total death of all causes among 50 y.o.s and above divided by total deaths of all causes

True or False

The proportionate mortality rates are useful in the case of an epidemic or pandemic

True or False

Higher swaroop index = poor health status of a community

Defined as the number of deaths (less than 1 y.o.) divided by the total number of live births

Defined as the number of deaths (less than 1 y.o.) among infants followed up divided by the total number of infants followed up

True or false

The absolute infant mortality rate is the most sensitive indicator of adequacy of immunization programs, nutrition, and pre-post natal services

Defined as the number of deaths (less than 28 days of age) divided by the total number of live births

Defined as the number of deaths (28 days of age to less than 1 y.o.) divided by the total number of live births

Defined as the number of deaths (28 weeks of gestation and over) divided by the total number of live births

True or false

The fetal death ratio is also knows as the still birth ratio

Defined as the total deaths of women directly related to pregnancy, labor and puerperium divided by the total number of livebirths

What is a more appropriate denominator when calculating maternal mortality ratio and what is the reason live births is used>

Defined as the total deaths from a certain disease divided by the total number of cases of that disease

Defined as the number of livebirths in a year divided by the average population

Defined as the no. of liverbirths per year over the number of women aged 15-44 y.o.

Defined as the total number of a disease at a certain point in time over the total population at the time

Defined as the total number of a disease at a certain period over the total population at that period

True or False

Prevalence rates provides an estimate of the risk of developing a disease

The true measure of risk or probability of acquiring a disease by a disease-free individual during the specified time period

Defined as the number of cases who developed the disease during a period over the no. of indivdiuals free of the disease during that period

Defined as the number of developing cases during a specific time period over the number of persons exposed to the risk of illness during the same period

Defined as the no. of new cases developing during an interval divided by the total persons exposed at the time of obervations

Papasa ka?

Sum of all values/sample size (n)

NSum of all values /population size (N)

Value that appears most frequent

Midpoint of all values

Measures how symmetric or non-symmetric the data are

The peakedness of the graph

Selection of a subset of the sampled population to represent the whole to generate estimates that can be validly generalized to the reference or target population

Population is divided into clusters

Extension of cluster/stratified sampling to several stages

Observe the relationship between the risk factors and disease on a population level
