Answer: B) Yes, especially if the people who are on a do dash not dash call registry have a trait that is not accurately represented by the remaining people in the sample
If the person conducting the survey wants a good random sample then they should take opinions from a broad audience, including people from different backgrounds, races, ages, cultures etc. In this case, the people that are not on the call registry most likely have a common trait that would explain why they're not in there (ie. they're too young to be eligible to be in the call registry, they are too old to be on the call registry, etc). Not calling them then would throw off the sample. Because of this, B is the correct answer.
Answer:
Variable Ratio Schedule
Explanation:
First, there are two different types of reinforcement:
The positive reinforcement applies a stimulus to increase the frequency of the desirable variable.
The negative reinforcement removes a stimulus to increase the frequency of the desirable variable.
However, the positive reinforcement divides itself in different types:
A continuous reinforcement schedule gives us a reinforcement every time we engaged in the desired conduct.
On the other side, the partial reinforcement schedule also divides itself in
And these divide themselves in fixed or variable.
- The fixed ratio schedule gives a reinforcement after a <u>fixed number</u> of desired responses.
- The variable ratio schedule gives a reinforcement after a <u>changing</u> <u>number</u> of desired responses.
- The fixed interval schedule gives a reinforcement after a <u>constant amount of time.</u>
- The variable interval schedule gives a reinforcement after a <u>variable amount of time.</u>
In the example, the rats get a pellet of food, so we're talking about a reinforcement. They <u>don't get a reward EVERY TIME</u> they press the bar so we are not talking about a continuous reinforcement but a partial reinforcement. Since the rats press the bar and get a reward after certain <u>NUMBER</u> of times, we're talking about a ratio schedule. Finally, the number of times they need to press the bar to get a reward <u>VARIES</u> from trial to trial so this is a Variable Ratio Schedule.

A bar chart, sometimes known as a bar graph, is a type of chart or graph that displays categorical data using rectangular bars with heights or lengths proportionate to the values they indicate.
<h3>What is a bar graph used for?</h3>
Bar graphs are used to compare data across groups or to follow changes over time. When attempting to measure change over time, however, bar graphs work best when the changes are big.
Bar graphs are a powerful graphic to utilize in presentations and reports. They are popular because they enable the viewer to identify patterns or trends far more simply than a table of numerical data.
Thus, Option C is what Dana should use.
