Whats the answer

Respuesta :

Answer:

Median and Mode.

Step-by-step explanation:

The data could be represented in table form in ascending order as:

 Number of meals                       Frequency

      2                                                     2

       3                                                     3

       4                                                     2

       19                                                    1`

On the basis of the data now we find the mean, median and mode:

Mean= average of the data

Mean=\dfrac{2\times 2+3\times 3+4\times 2+19\times 1}{2+3+2+1}=\dfrac{40}{8}=5

Hence mean is 5.

Median is the central tendency of the data

on looking at our data we see that the Median=3.

also the mode of the data is the entry corresponding to the highest entry.

Hence the highest frequency is 3 and the corresponding value is 3.

Hence, Mode=3

Hence, the most appropriate measure of center for this situation is :

Median and Mode.
