| Question | Answer |
|---|---|
| Parameter | A characteristic of the population to be measured or observed in an observational study |
| Variables such as Body weight or employee's salary or age are | Numerical/ Quantitative variables |
| Entire group of individuals of interest is | Population |
| Subgroup of the entire group of individuals is | a sample |
| A numerical measure that describes the aspect of the entire population is | a parameter |
| Numerical measure obtained from a sample is | a statistic |
| A level of measurement, we can put the data into categories is | nominal level |
| We can order the data from smallest to largest at the | ordinal level |
| We can order the data and also take the differences between data values at the | interval level |
| We can order the data, take the difference and also find the ratio between data values at the | ratio level |
| Consists of information coming from observations, counts, measurements, or responses | Data |
| The science of collecting, organizing, analyzing, and interpreting data in order to make decisions | Statistics |
| A _______ is a collection of all individuals or objects counts that are of interest | Sample |
| A numerical description of a population characteristic | parameter |
| A numerical description of a sample characteristic | Statistic |
| The branch of statistics that involve the organization, summarization, and display of data | Descriptive Statistics |
| The branch of statistics that involves using a sample to draw conclusions about a population. A basic tool in the study of inferential statistics is probability | Inferential Statistics |
| Consist of attribute, labels, or nonnumerical entries | Qualitative |
| Consist of numerical measurements or counts | Quantitative |
| A study in which the person conducting the study observes characteristics of a sample selected from one or more existing populations | Observational study |
| A study in which the person conducting the study looks at how a response variable behaves different under different conditions. These conditions are assigned by the person conducting the study | Experiment |
| A sample in which every sample of the same size n in the population has an equal chance of being selected is called a | Simple Random Sample |
| Using a group of pre-generated random numbers, you can form a | Sample |
| Dividing the population into distinct subgroups that have commonalities and then drawing random samples from each subgroup | Stratified Random Sampling |
| Sequentially numbering all the individuals in the population and then form a randomly selected starting point, taking every kth member from the sample | Systematic Random Sample |
| Dividing the population into clusters that are only related by location and then making a random selection of clusters | Cluster Sampling |
| Creating small groups stage by stage using various sampling methods, with the final sample consisting of clusters is called | Multistage |
| The list of members from which a sample is actually select is called | Sampling Frame |
| Since part of the population is omitted in the selection, ____________ ____ occurs | Selection bias |
| Data is collected from all individuals in the entire population | Census |
| The variables that have values that are controlled by the experimenter also known as factors | Treatments |
| A study in which one or more explanatory variables are manipulated in order to observe the effect on a response's variable | Experiment |
| Those variables that the experimenter thinks may be affected by the explanatory variables. It is measured as part of the experiment but is not controlled by the experimenter | Lurking variables |
| Any particular combination of values for the explanatory variables. These are also called treatments | Experimental conditions |
| The smallest entity to which a treatment is applied | Experimental Unit |
