CCSS.L.9-10.4C

Match the following:

• Stratified Random Sample

• Involves the division of a

  population into smaller groups.

  Ideally, there is heterogeneity within each

  group. Data are collected

  from all observations in the selected group.

• Systematic Random Sample

• The

  division of a population into separate groups based on shared attributes or

  characteristics (homogeneous grouping).

  A simple random sample is

  selected within each group, and the selected units are combined

  to form the sample.

• Simple Random Sample (SRS)

• A method in which sample members from a population are selected according to a random starting point and a fixed, periodic interval.

• Judgement Sample

• A non-probability sampling technique where the researcher selects units to be sampled based on their own existing knowledge.

• Cluster Random Sample

• A sample in

  which every group of a given size has an equal

  chance of being chosen.

CCSS.W.9-10.2D

Match the following

• x

• A variable whose values are used to explain or

  predict corresponding values for the response variable.

• y

• Dependent Variable symbol

• Independent Variable

• A variable whose values are explained or predicted by the explanatory variable

• Confounding Variable

• A variable that is related to the explanatory

  variable and influences the response

  variable and may create a false perception of

  association between the two.

• Dependent Variable

• Independent Variable symbol

Match the following

• Double-Blind Study

• Treatments are assigned to experimental units

  completely at random.

• Randomized Complete Block Design

• Subjects do not know which treatment they are receiving, but members of the research team do, or vice versa.

• Single-Blind Study

• Neither the subjects nor the members of the research team who interact with them know which

  treatment a subject is receiving.

• Matched Pairs Design

• A special case of a randomized block design. Using a blocking variable, subjects (whether they are people or not) are arranged in pairs matched on relevant factors.
