The mean deviation of the number of pets Ramiro surveyed as shown in the table attached below is: D. 1.12
To find the mean deviation of the number of pets, the following steps would be taken:
- Find the mean, which is sum of each frequency and score (fx) divided by the total number of pets. [tex]\mathbf{(\frac{\sum fx}{n} )}[/tex]
- Subtract the mean from each score, [tex]\mathbf{( x - \bar x)}[/tex]
- Sum the deviations together and divide by total number of pets.
- The formula for the mean deviation is given as: [tex]\mathbf{\frac{\sum f* |x - \bar x|}{n} }[/tex]
Mean deviation as solved in the table attached in the image below would be:
[tex]\mathbf{\frac{33.6}{30} = 1.12}[/tex]
Therefore, the mean deviation of the number of pets Ramiro surveyed as shown in the table attached below is: D. 1.12
