Question
Descriptive statistics are used to:
Question 24 options:
compare the signficance of the difference between 2 data sets
test the difference between the means
describe the observations
describe the type one error in an experiment
Which of the following is not a characteristic of the normal curve:
Question 25 options:
bell-shaped
represents 100% of the scores under the curve
100 is at the center
allows us to determine rank
What are inferential statistics used for?
Question 23 options:
summarize the mean and standard deviation of the data
estimate if differences between groups are by chance
describe the data from 2 unrelated groups
describe the relationship within a set of data

Explanation / Answer
Descriptive statistics are used to
describe the observations.
Explanation:
Descriptive statistics is the term given to the analysis of data that helps describe, show or summarize data in a meaningful way such that, for example, patterns might emerge from the data. Descriptive statistics do not, however, allow us to make conclusions beyond the data we have analysed or reach conclusions regarding any hypotheses we might have made. They are simply a way to describe our data.
Descriptive statistics are very important because if we simply presented our raw data it would be hard to visulize what the data was showing, especially if there was a lot of it. Descriptive statistics therefore enables us to present the data in a more meaningful way, which allows simpler interpretation of the data.

Explanation:
larger population of all UK students. Properties of samples, such as the mean or standard deviation, are not called parameters, but statistics. Inferential statistics are techniques that allow us to use these samples to make generalizations about the populations from which the samples were drawn. It is, therefore, important that the sample accurately represents the population. The process of achieving this is called sampling (sampling strategies are discussed in detail here on our sister site). Inferential statistics arise out of the fact that sampling naturally incurs sampling error and thus a sample is not expected to perfectly represent the population. The methods of inferential statistics are (1) the estimation of parameter(s) and (2) testing of statistical hypotheses.
