Answer:
(C) Mean absolute deviation
Step-by-step explanation:
Mode: Mode is the number which appears many times in the data set.
Mean absolute deviation: The mean absolute deviation (MAD) of the data set is the average distance between each data value and the mean.
Median: Median is the middle value of the given data set.
Range: Range is the difference between the lowest and the highest values of the given data set.
Since, the given statement is the definition of the Mean absolute deviation, therefore option C is correct.
Answer:
The outcome of guessing the correct answers to a 50 question test is 12.5.
Step-by-step explanation:
Let us first consider one question.
Since it has 4 options so we can say that;
Total number of possible outcomes = 4
Since 1 answer is correct so we can say that;
Favorable outcome = 1
Now we can say that;
Probability for choosing correct answer can be calculated by Favorable outcome divided by Total number of possible outcomes.
framing in equation form we get;
![P(Correct\ Answer) = \frac{1}{4}](https://tex.z-dn.net/?f=P%28Correct%5C%20Answer%29%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
Now Given:
Total number of question = 50
So we can say that;
Total number of correct answer out of 50 is equal to Probability for choosing correct answer multiplied by Total number of question.
framing in equation form we get;
Guessing number of correct answer out of 50 = ![\frac14 \times 50 = 12.5](https://tex.z-dn.net/?f=%5Cfrac14%20%5Ctimes%2050%20%3D%2012.5)
Hence The outcome of guessing the correct answers to a 50 question test is 12.5.
