Chapter No. 01: The Importance of Statistics in the Criminological
Sciences or Why Do I Have to Learn This Stuff?
1. If a systematic random sample is selected using a list that is not ordered in any way,
the results should be similar to a sample selected using a simple random sample.
2. Multistage cluster sampling techniques can be used to select a random probability
sample when there is no population list available. You actually work toward the
sample you want by extracting a sample of groups or clusters that are available,
and then sampling the elements of interest from these selected clusters.
3. The goal in obtaining or selecting a sample is to select it in a way that increases the
chances of this sample being representative of the entire population. Using
probability sampling techniques not only serves to minimize any potential bias
we may have when selecting a sample, thereby making our sample more
representative of the population, but also allows us to gain access to probability
theory in our data analysis. This body of mathematical theory allows us to
estimate more accurately the degree of error we have when generalizing results
obtained from known sample statistics to unknown population parameters.
4. The fundamental element in probability sampling is random selection. When a
sample is randomly selected from the population, all the elements of the
population have a known, equal, and independent chance of being selected for
the sample. All probability sampling methods rely on a random selection
procedure.
5. We could use the probability sampling technique of selecting a weighted sample or
the nonprobability sampling technique of quota sampling.
,6. The danger in using nonprobability samples is that they may not be representative of
the population. This means that the generalizations we make from our sample to
the population may be wrong.
7. Nonprobability samples are appropriate when we want to sample a unique
population, such as gang members or other deviant individuals, who are not
available from some population list. Purposive/judgment samples and snowball
samples are often used in these cases. In addition, if your research is exploratory
in nature, it is appropriate to use a nonprobability sample.
8. Reliability is when you obtain consistent scores on different occasions. This suggests
that the instrument you are using to capture the phenomenon under inquiry is
capturing a consistent amount of it. Reliability is important because you need to
be able to capture the phenomenon under study consistently across domains.
9. Measurement validity means that you have measured what you intended to
measure. A measure is reliable if it gets consistent results on different
occasions, provided what you are measuring has not changed.
Measurement validity is important, because if your instrument is not
capturing what you intend it to, then your results may not be valid.
10. This is an example of snowball sampling. One respondent leads the researcher to
others and then those respondents lead researchers to more respondents.

1. Quantitative; interval/ratio; b. Quantitative; interval/ratio; c. Quantitative;
interval/ratio; d. Qualitative; nominal; e. Qualitative; nominal; f. Quantitative;
interval/ratio.
2. The categories of a variable measured at the ordinal level of measurement can be
ordered, but the distance between the categories is not quantifiable. Categories
for interval-level variables have a known and equal distance between them. In
addition to this, ratio-level variables have a true and meaningful zero point.
3. Arrest is the independent variable, and future drunk-driving behavior is the
dependent variable.
4. Gender is the independent variable, and fear is the dependent variable.
5. The numerator would be the number of victimizations against people 14-18 years old,
and the denominator would be the total population of people 14-18 years old.
6. Rates allow you to make comparisons across different places and time using a
standardized unit. For example, city A may have reported 100 homicides while
city B reported 300 homicides in the past year. However, city A has a population
of 100,000 while city B has a population of 500,000. The homicide rater for each
city is, respectively, 100 and 20 per 100,000. Without taking the rate, we would
prematurely conclude that city A was more violent when in fact city B is more
violent.
