Experimental Designs
Keeping other variables constant for all experimental units
What is a Control?
A group of individuals that you are wanting to collect and research information upon.
What is a Population?
A set study that is collecting data from the sample, to give information about the population.
What is a Sample Survey?
You take a sample and when you take the sample you make sure that every sample has the same size and the same chance of being chosen.
when you imitate chance behavior, based on a model that accurately reflects the situation.
What is a Simulation?
A part of a population that you are analyzing to make a conclusion about the population that you took from.
What is a Sample?
When a sample you have pulled overstates and understates the sampling probability than others.
What is Sampling Bias?
In this sampling method, you break the population into select groups that correlate then to study each group you split the groups into simple random samples.
What is a Stratified Sample?
You observe more and more repetitions of any chance process, the proportion is going to approach a single value.
What is Law of Large Numbers?
Experimental units that are assigned to treatments using a chance process
What is Random Assignment?
A set or made design is looking at two or more treatments and if they are viable.
What is Comparison?
In this issue, you have some members who are less likely to be chosen or cannot be chosen in the sample.
What is Under Coverage?
A car company sends a survey to a car dealership asking about their thoughts on the new vehicles that they have produced.
What is Convenience Sampling?
a model you made you are tossing a 2 sided chip one with a shiny side and one with a blank side and you record all the possible combos.
What is a Probility Model?
A design that allows you to draw separate conclusions about each category, and analyze differences in response based on the category.
What is a Block Design?
A data value that describes the features of a population+ a data value that describes the features of a sample
What is Parameter + Statistic?
A new reality tv show that sets people up to join their dream job reaches out to their viewers on who they think should obtain their dream job.
What is Voluntary Response?
What is Cluster Sample?
You should use these models when you are trying to find the probability of two events, that you have categorized and are analyzing the data.
What is Two-way table and Venn Diagrams?
A block design that compares categories with treatment and two units/subjects allows the subjects to serve as their own control.
What is a Matched Pairs Design?
When you are able to repeat an experiment on many subjects/units and receive similarly or the same results with low variation.
What is Replication?
You submit a survey digitally to 1000 people and ask whether they like hots dogs or hate hot dogs, 800 people respond back and 700 like hot dogs, it is predicted that 200 people who did not respond back hate hotdogs?
What is Non-Response Bias?
In this sampling method, you number your population, with your numbered population a starting number is randomly selected and you select a person every person counting from the chosen number.
What is a Systematic Sample?
when all the probability of a given probability table all adds up to the values one, for example, .55 +.15+.20+.10=1 data for the probability table this is.
What is a Legitimate Probability Model?
