Question

Identify each sample, and determine a population from which it was selected. Then classify the type of data collection used.

 

A frozen food company is considering creating frozen meals with tofu instead of meat. At a test, they randomly give half of a group of 100 people the meals with meat and the other half the same meals with tofu and ask the people how they like the meals.

Step-by-Step Solution

Answer

Sample: Group of 100 people at the testing.

Population: All people at the testing.

Type of data collection: Experiment.

Step 1. State the concept for sample and population.

A sample is a specific group that you will collect data from. The size of the sample is always less than the total size of the population.

A population is an entire group that you want to draw conclusions about.

a population doesn’t always refer to people. It can mean a group containing elements of anything you want to study, such as objects, events, organizations, countries, species, organisms, etc.

Step 2. State the concept for data collection .

Data collection is the process of gathering, measuring, and analyzing accurate data from a variety of relevant sources to find answers to research problems, answer questions, evaluate outcomes, and forecast trends and probabilities.

Step 3. State the answer with an explanation .

Here, the sample is the 100 people who try the meals and the population is all people at the testing. Since the food company draws conclusions about the preference of each item after the testing, the method of data collection is an experiment.
