Handout Master 1.4 Understanding Correlations Correlational studies show relationships between variables. If high scores on one variable predict high scores on the other variable‚ the correlation is positive. If high scores on one variable predict low scores on the other variable‚ the correlation is negative.

The relationship of interest could be either a D relationship or an R relationship‚ so this might involve making a bar graph and computing D or making a line graph

Introduction The main theory of the experiment is that an object needs an amount of heat for it to change a unit mass by 1 degree in temperature. The objectives of the experiment are to determine the specific heat of metal specimens using the method of mixture‚ to measure the equipment properly‚ to carefully measure the temperature of the equipment‚ to be patient while waiting for the output of the experiment and to be precise in computing for the specific heat of the specimen.
