All statistical tests are part of Inferential analysis; there are no tests conducted in Descriptive analysis · Descriptive analysis- describes the sample's characteristics using… o Metric- ex. sample mean, standard deviation or variance o Non-metric variables- ex. median, mode, frequencies & elaborate on zero-order relationships o Use Excel to help determine these sample characteristics · Inferential Analysis- draws conclusions about population o Types of errors o Issues related to null and alternate hypotheses o Steps in the Hypothesis Testing Procedure o Specific statistical tests
Descriptive statistics give information regarding a data set. For example, any graph, the mean, median, and mode, standard deviation, range, and variance are all descriptive statistics. Inferential statistics is using a representative sample from a population to say something about that population. For example, for presidential polls, not everyone in the country is called and asked who they plan to vote for. Whoever does the surveying picks a sample that should fairly represent the population as a whole, and just asks those people. Depending on the sample size, the surveyor can then determine how accurate the results are, and use them to generalize to the population as a whole.

Yes they do.
No, descriptive data is not a technique; it is data that describe the sample such as mean, SD, mode, and range.

A numerical value calculated for a sample is called a descriptive statistic.
Not necessarily. The UK Census (not sample) collects descriptive statistics such as level of education, ethnic identity, religious beliefs and so on.
