Chapter 1: Q3-16BSC (page 1)

In Exercises 9鈥�20, identify which of these types of sampling is used: random, systematic, convenience, stratified, or cluster.

Deforestation Rates Satellites are used to collect sample data for estimating deforestation rates. The Forest 91影视 Assessment of the United Nations (UN) Food and Agriculture Organization uses a method of selecting a sample of a 10-km-wide square at every 1o intersection of latitude and longitude.

Short Answer

Expert verified

Systematic sampling

Step by step solution

01

Given information

Sample data collection is done by the satellites to generate an estimation of the deforestation rates.

The 10 km wide square area is recorded at every 1-degree intersection of latitude and longitude.

02

Step 2:Identify the method of sampling

In systematic sampling,the sample observations are taken from the population, systematically selecting the initial point randomly.

In this case, the systematic order is followed to observe each sample of 10 km wide square area. The subsequent sample areas are selected at every 1-degree intersection of latitude and longitude, assuming the first selection is done using randomization.

Thus, the sampling method is systematic sampling.

MCAT The Medical College Admissions Test (MCAT) is commonly used as part of the decision-making process for determining which students to accept into medical schools. To test the effectiveness of the Siena MCAT preparation course, 16 students take the MCAT test, then they complete the preparatory course, and then they retake the MCAT test, with the result that the average (mean) score for this group rises from 25 to 30. There is a 0.3% chance of getting those results by chance. Does the course appear to be effective?
