This type of Statistics uses graphs and tables to organize and display data.
Descriptive Statistics
100
This type of data labels, sorts and organizes data based on their Character Traits or Qualities
Categorical Data

Jane Goodall was famous for her study of primates in their natural environments. She would watch and recorded how they interacted with each other. She tried never to be seen or to interfere with their habitats. What type of study did Jane engage in?
Jane conducted Observational Studies.

Picking names out of a hat. Assigning each person a number, then having a cpu generate a list of numbers. These are examples of ...
Simple Random Sampling
100
This method creates groups to isolate the effects of extraneous variables
Blocking
200
This type of Statistics uses data taken from a sample and creates predictions about how the population will behave.
Inferential Statistics
200
When things are counted or measured, we are using this type of data...
Numerical Data
200
In this type of study, the researcher assigns a treatment to participants and measures their reaction.
Experimental Study (Experiment)
200
This is the type of sampling that is always biased. You use the people who are in your vicinity. You use only the people who call into your show. You use only the people choose to visit your website and fill out your online survey. What type of sampling is this?
Convenience Sampling
200
This is also known as the independent variable, the treatment being tested or the object controlled by the researcher.
Explanatory variable

Chelsea is reading a data table and she identified that the average score for the data set was an 80. What type of statistics is she using?
The average pertains only to the data in front of her. This is Descriptive Stats.
300
Things like your zip code or the area code are what types of data?
Categorical data
300
In this type of study participants report how often they exhibit a certain behavior. The researcher records and organizes the data. What type of study is this?
Observational Study
300
In this type of sampling we create homogeneous groups. Then we select a few from each of these groups for testing.
Stratified Sampling
300
When the effects of variables are so intertwined that cause of the change cannot be separated, the explanatory variable and the extraneous variable are said to be ....
Confounded

After looking at the graph of recent student attendance, Dr. Tossman predicted that the school would have 95% attendance next week. What type of Statistic is this?
Dr. Tossman is making predictions about what will happen, based on the data of what has happened. This is Inferential Stats.
400
Height, Weight, and Wingspan are examples of which kind of data?
Numerical Data
400
Cause and Effect claims can always be made from the results of this type of study.
Experimental Study
400
After creating a bunch of diverse groups (heterogeneous), we select a few groups and test everyone in those selected groups. What type of Sampling is this?
Cluster Sampling
400
This is the value being measured in an experiment. These are the results of the value you changed as a researcher.
Response Variable
500
The Mean, Median and Mode of a data set are used to anticipate how many of each new sweater and the quantity of each colors to buy for the stores sale. Were the Mean, Median, and Mode used as Inferential or Descriptive Statistics?
The Mean, Median and Mode are themselves Descriptive stats BUT they were used as Inferential Stats to anticipate the needs of the store.

Numerical Data can be split into 2 subcategories, what are those subcategories? Describe each.
Discrete - Having a predictable terminating value. Specific, set, predictable pattern of values Continuous - Values can have any number of decimals, the values do not always terminate at a specific place value
500
This type of study can only result in claims that a relationship exists between the explanatory and response variables.
Observational Study
500
After choosing a starting point, you will sample 1 out of every 8 cupcakes baked by Melissa. What type of sampling is this?
Systematic (Random) Sampling
500
Extraneous Variables are...
Extraneous Variables are variables that (in addition to the Explanatory Variable) may also influence the response variable.
