Intro to Statistics | Types of Data | Research Processes |
---|---|---|
What are parametric statistics?
These types of statistics are used to make valid generalizations or inferences about population parameters.
|
What is the level of measurement?
This determines which summary statistics, graphs, and analysis are possible and sensible.
|
What is the first step in the Process of Data Analysis?
The first step in this process is having a hypothesis about a population of interest.
|
What is a t-test?
The parametric statistic that allows you to look at the difference between group means.
|
What is nominal data?
Also known as categorical or qualitative, this level of measurement is the most basic and includes descriptions or labels. Sex is an example.
|
What are Descriptive Statistics?
The statistics that help us understand the characteristics of the sample we collected. For example, the mean age of your sample.
|
What are a non-parametric statistics?
These statistics makes no assumptions that the data or population have any characteristic structure.
|
What are the intervals between the values in the scale?
In ordinal data, although there is a meaningful order to the data, THIS may not be equal. For example, first versus second versus third place in a race.
|
What is the process of making inferences ?
The generation of p-values and confidence intervals are generally necessary in this process.
|
What is the assumption of homogeneity of variance (also accepted: assumptions of normality, linearity, or independence)?
A non-parametric statistical approach is advised when this has been violated.
|
What are the mean, median, and standard deviation?
The most precise level of measurement, interval/ratio, also known as scale, quantitative, and parametric, can be used to calculate which common basic statistics?
|
What is making inferences based on p-value?
Statistics, research design, other research results, and clinical knowledge must all be considered when doing this.
|
What is an approximation?
Everything we do in statistics is this.
|
What is a column chart (in logical order)?
This is the type of graphical representation that should be used to display the results of a satisfaction survey, which include a Likert scale from very unsatisfied to very satisfied.
|
What is the Scientific Process?
Observation, pattern, question, hypothesis, experiment and conclusion are the six steps involved in this process.
