What is the effect of an outlier on the mad (mean absolute deviation) of a data set.

choice a) an outlier does not change the mad.
choice b) an outlier always increases the mad.
choice c) an outlier always decreases the mad.
choice d) an outlier can either decrease or increase the mad.

personally, i'm debating between choices b and d. what do you think?

the effect of an outlier is )( an out lier can either decrease or increase mad

i hope this is really helpful!

x = 23.78

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
