Heya, ive got my basic skills on mon, just wondering what sort of things will be on to give me time to have a little revise? If i can remember rightly, mean, mode, median and range is on a basics test? Mean= add them all up and divide by how many Mode= The most frequent Medean= Put them all in order and its the one in the middle Cant really remember range, is it highest take away the lowest? Ermm, really cant remember ratios and percentages and measurements, unless there really simple :/ i only did a test last year to get my grade to a c!! dear me lol! And i hate divisions unless there really basic lol!!
