Answer:
The method used above is convenient sampling.
Explanation:
- With convenient sampling, the data to be sampled is picked randomly among the relevant population that is close to hand.
- The randomly picked population acts as samples through which the analysis is done and later on a conclusion reached out of the results.
- In the given context, the researcher obtains data of 45 students from the , this is the close at hand data that he uses, this is the readily available data with which he can conduct his research.
- This makes the research a convenient method type.
Answer:
Escape training/conditioning.
Explanation:
The <em>Skinner box</em> or operant conditioning chamber is a <em>laboratory system created to study animal behavior by American psychologist B. F. Skinner</em> (March 20, 1904 – August 18, 1990).
It has a mechanism that <u>conditions</u> animal behaviour by subsequent introduction of reward or punishment. In this example, the rat is <u>conditioned or in other wards is trained to escape punishment</u> in the form of the electric shock by pressing the bar.
Answer: MAPE
Explanation: MAPE (Mean Absolute Percentage Error (MAPE) is a statistical measure of how accurate a forecast system is. It measures the size of the error in percentage terms.This scale sensitivity renders the MAPE close to worthless as an error measure for low-volume data where as MAD (Mean Absolute Deviation) measures the size of the error in units. Hence MAPE would be a more meaningful measure of forecast accuracy.

Dynamic Study Modules function by continually evaluating your performance and activity, utilizing data and analytics to give customised information in real-time to reinforce ideas that target each student's unique strengths and weaknesses, and finally reviewing your performance and activity again. In order to provide a learning method that is particularly successful, Dynamic Study Modules draw on research from the domains of cognitive psychology, neurobiology, and game studies. Dynamic Study Modules continually evaluate your performance and provide you more practice in the regions where you struggle the most using a highly tailored, algorithmically driven method. Each Dynamic Study Module encourages quick learning and long-term memory retention and may be accessed through computer, smartphone, or tablet.
