The weekly allowance of 6 students are $5, $3, $6, $5, $9 and $5. what measurement of central tendency are shown by the $5 values

Mode and Median

Step-by-step explanation:

First of all, lets order the values in increasing order:

3 - 5 - 5 - 5 - 6 - 9

5 is the most common value, known as MODE.

But it also shows the half of the distribution., this is, what is the value that the divides the hall poorer and the half richer. Said in another way, 50% of the students earn $5 or less. This is call the MEDIAN.

5 can not be the mean, as the sum of all values is $33 so the mean is $33/6 = $5.5

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
