What is a descriptive statistic? What is an inferential statistic? 2) What is the difference between self-report data and formal records? What is evaluation apprehension, social desirability bias, and coverage error. To which type of research do they present the greatest threat? Why is survey research so popular?

1.

A descriptive statistic is a summary statistic that quantitatively describes or summarizes features from a collection of information, while descriptive statistics is the process of using and analysing those statistics.

Statistical inference is the process of using data analysis to deduce properties of an underlying distribution of probability. Inferential statistical analysis infers properties of a population, for example by testing hypotheses and deriving estimates.

a. Conceptually, official records of crime are measures of law enforcement reactions to crimes that come to their attention. In contrast, self-report measures were developed as a more direct measure of criminal behavior, a measure that better captures the conceptual domain of crime. It is based on victims and offenders' own reports of their involvement in criminal acts, whether known to law enforcement agencies or not. Self-report measures are thus an alternative measure of crime that is conceptually a more direct measure of criminal behavior, captures crimes known and unknown to law enforcement, and avoids the selective reporting and processing biases potentially inherent in the more limited official record measures of responses to crime. It has become the mainstay in criminological research, particularly in etiological studies.

b. The evaluation apprehension theory was proposed by Nickolas B. Cottrell in 1972. He argued that we quickly learn that the social rewards and punishments that we receive from other people are based on their evaluations of us. On this basis, our arousal may be modulated.

c. In social science research, social desirability bias is a type of response bias that is the tendency of survey respondents to answer questions in a manner that will be viewed favorably by others. It can take the form of over-reporting "good behavior" or under-reporting "bad", or undesirable behavior.

d. Coverage error is the error in an estimate that results from failure to include specified units in the conduct of a survey (undercoverage), and inclusion of some units erroneously either because of a defective frame or because of inclusion of unspecified units or inclusion of specified units more than once in the.

e.

Survey research is popular because of its versatility, efficiency and generalizability ... Survey methods lend themselves to probability sampling from large populations. Thus it is appealing when sample generalizability is a central research goal.

Answer:1) A descriptive statistic is a summary statistic that quantitatively describes or summarizes features from a collection of information, while descriptive statistics is the process of using and analysing those statistics.

1b) Statistical inference is the process of using data analysis to deduce properties of an underlying distribution of probability.

2. In self report the individual evaluates his/herself while other formal records involve third party evaluation

3. a) Evaluation Apprehension. By Peter Lloyd. In the lexicon of psychology, evaluation apprehension theory predicts that when we work in the presence of others, our concern over what they will think can enhance or impair our performance.

b) In social science research, social desirability bias is a type of response bias that is the tendency of survey respondents to answer questions in a manner that will be viewed favorably by others.

c) Coverage error is a type of non-sampling error that occurs when there is not a one

The type of research they threaten most is the descriptive type of research

4. Survey research is popular because of its versatility, efficiency and generalizability.
