1. Natural zero - ANSWER ✔ Where none of the quantity is present. The zero
starting point makes ratios meaningful
2. Ratio level of measurement - ANSWER ✔ the sum of 2 data values are
meaningful & the data can be arranged in some kind of order. Does have a
natural zero starting point.
ex. distance, price, etc
3. Graphs - ANSWER ✔ statistical data presented in visual form
4. Biased samples.. - ANSWER ✔ are not representative of the population.
5. Correlation & casualty - ANSWER ✔ one of the variables "causes" (or
directly affects) the other variable
6. Correlation - ANSWER ✔ when 2 variables have a relationship, are linked
together & make sense.
Correlation does not imply casualty
,7. Loaded questions - ANSWER ✔ survey questions intentionally worded to
elicit a desired response.
Order of questions in a survey can also intentionally elicit a desired
response.
8. nonresponse - ANSWER ✔ when someone refuses to respond to a survey
question or is unavailable
9. self-interest study - ANSWER ✔ a survey in which the sponsor can enjoy
monetary gains from its results
10.If sample data is not collected in an appropriate way.. - ANSWER ✔ the
data may be useless & no amount of statistical tutoring can salvage them.
11.2 types of study: - ANSWER ✔ observational study & experiment
12.2 ways in which the science of stats is used for deception : - ANSWER ✔
Evil intentions & unintentional errors
13.Observational study - ANSWER ✔ We observe & measure specific
characteristics but don't attempt to modify the subjects being studied
14.Experimental study - ANSWER ✔ We apply treatment & proceed to
observe its effects on the subjects
15.Experimental units - ANSWER ✔ The subjects used in experiments, the
subjects being experimented on
16.It is important to select a sample of subjects .. - ANSWER ✔ Where it is
likely to represent the larger population
17.Simple random sample - ANSWER ✔ Every subject within the selected
sample has an equal chance of being chosen
18.Random sample - ANSWER ✔ Every individual member of the population
has an equal chance of being chosen
,19.Probability sample - ANSWER ✔ Members of the population have a known
chance of being selected
20.Systematic sampling - ANSWER ✔ Where you select a starting point &
select every nth person in the population
21.Convenience sampling - ANSWER ✔ Using results that are very easy to get
22.Stratified sampling - ANSWER ✔ Subdivide The population into 2 different
groups (strata) where subjects share the same characteristics. Then draw a
sample from each subgroup (stratum)
23.Cluster sampling - ANSWER ✔ Divide population into groups/clusters,
randomly select some of those clusters & choose all members from selected
clusters
24.Multistage sampling - ANSWER ✔ Collecting data using a combination Of
basic sampling methods
25.Cross sectional study - ANSWER ✔ Data is observe, measured, & collected
at one point in time
26.Retrospective / Case-Control study - ANSWER ✔ Data is collected from the
past through examination of records, interviews, etc
27.Prospective / Longitudinal/Cohort study - ANSWER ✔ Data is collected in
the future from groups sharing common factors
28.Cohorts - ANSWER ✔ Groups of people sharing common factors
29.Randomization - ANSWER ✔ When subjects are assigned to different
groups through random selection. Use chance as a way to create 2 groups
that are similar
30.Replication - ANSWER ✔ The repetition or duplication of an experiment so
that results can be confirmed or verified.
31.The repetition of an experiment on more than one subject.
, 32.Blinding - ANSWER ✔ A technique where the subject doesn't know
whether they are receiving a treatment or a placebo effect
33.Double-Blind - ANSWER ✔ Blinding occurring at 2 levels
34.Confounding - ANSWER ✔ Occurs in an experiment when you're not able
to distinguish the effects of different factors
35.Completely Randomized Experimental Design - ANSWER ✔ Assign
subjects to different treatment groups through random selection. Use
randomness to determine who gets treatment
36.Randomized Block design - ANSWER ✔ A group (block) of subjects that
are similar but differ in ways that might affect the outcome of The
experiment.
So form groups of subjects with similar characteristics & randomly assign
treatments to the subjects within each block
37.Rigorously Controlled design - ANSWER ✔ Assign subjects to different
treatment groups so that those given treatment are similar
38.Data - ANSWER ✔ collections of observations
ex. measurements, genders, survey responses, etc
39.Statistics - ANSWER ✔ The science of planning studies & experiments,
obtaining data then organizing, summarizing, presenting, analyzing,
interpreting, & drawing conclusions based on that data.
Making inferences/generalizations about a population
40.Population - ANSWER ✔ complete collection of all individuals to be
studied
ex. measurements, scores, people
41.Census - ANSWER ✔ collection of data from every member of the
population, collecting data from all individuals
