Help me with finding the MAD for math please!!!!
1 answer:
The average (mean) absolute deviation of a data set is the average of the absolute deviations from a central point.
so we need to calculate the mean of this data set firstly:::
the mean of (7,10,19,14,3) =
then we will calculate how far each record is from this mean:::
7-10.6 = - 3.6
10-10.6 = - 0.6
19-10.6 = 8.4
14-10.6 = 3.4
3-10.6 = - 7.6
BUT as it requires the ABSOLUTE mean deviation, we will take the absolute values of the previous results
3.6 & 0.6 & 8.4 & 3.4 & 7.6
Adding them together and divide by the records number (5)::
ABSOLUTE mean deviation =
Done!!!

Hello! Recall you need to write complete questions in order to find exact answers. So in this problem I'll assume the question is:
<em>A number d minus 4 is less than -1</em>
<em />
So it is easy to know that we need to write an inequality here because of the words "less than", which implies that we must use the symbol <. So let's solve this step by step.
Step 1. A number d minus 4.
This statement includes the word "minus", so we need to use the symbol (-). Therefore:
Step 2. A number d minus 4 is less than
As we said above, here we need to use the symbol (<). So:
Step 3. A number d minus 4 is less than -1
Finally, we get:
