Census Simulation Experiments Sampling

Choose the study types of sampling that is most likely to be used: Simulation (SIM)  Census (CEN)     or Sampling (SMP): We want to estimate the number of cups and dishes for the coming new year party. 

• SIM (conducting real-world experiments is impractical, expensive, or dangerous.)

• CEN (collects data from every individual or unit in a population... "how much or how many")

• SMP (select a subset of individuals or items from a larger population: by doing math: calculate... or by average)

Choose the study types of sampling that is most likely to be used: Simulation (SIM)  Census (CEN)     or Sampling (SMP): We want to know how many pens and pencils you bought from a school supply store before the school year.

using a mathematical or physical model to reproduce the conditions of a study

• simulation

• survey

• randomization

• replication

survey that counts all the population

• confounding variable

• blinding

• census

• bias

What type of sampling is shown?

• Simple Random Sample

• Systematic Sample

• Cluster Sample

• Stratified Sample

Suppose that 25 percent of women and 22 percent of men would answer yes to a particular question. In a simulation, a random sample of 100 women and a random sample of 100 men were selected, and the difference in sample proportions of those who answered yes, was calculated. The process was repeated 1,000 times. Which of the following is most likely to be a representation of the simulated sampling distribution of the difference between the two sample proportions?

This is a method of research where an investigator manipulates one or more factors (independent variables) to observe the effect on some behavior or mental process (the dependent variable).

• Experiments

• Case Study

• Survey

• Observational

• Correlational

Suppose we want to select two students at random for a committee from a high school class containing 25 students.  If we evaluate the following random numbers two at a time from left to right, which two "students" would be selected?
Suppose we code each student with a unique number from 01-25:
47032 41279 01249 34887 23573 35207

• 47 & 23 

• 03 & 24

• 24 & 12

• 4 & 7

The process of gathering information/data from EACH member of the population.

• Census

• Interview

• Survey

• Questionnaire

Sampling method that consists of n individuals from the population chosen in such a way that every individual has an EQUAL chance of being selected.

• Stratified Sampling

• Simple Random Sampling (SRS)

• Cluster Sampling

• Systematic Sampling
