Oh locus isn't too difficult

if you have a dot like so . <-- then if the question says draw a locus around that dot you draw a circle because at all points the locus must be the same distance away from the point


not very good but you can see the locus around the dot is a circle yes?

the locus around a line is as shown below in the attachment

use a compass and draw the curve ok? don't do free hand like i did in paint xD

if you got any questions about locus just post them in the maths forum and someone will answer it ^-^

sure part 1 is testing if you know what mode means

Spoiler

part 2 is testing where the middle person is and which section of annual pay they fit into

Spoiler

part 3 is testing if you can work out a mean from the values given

Spoiler

part 4 is testing why it's an estimate

Spoiler

if you didn't quite get me look at this page
