Co Relational Methods Advantages And Disadvantages

Assignment 1 Test One

1. Compare experimental and co relational methods. What are the advantages and disadvantages of each? Show by an example how both methods could be used to investigate the same problem.

Co relational method is a scientific procedure that is used to look for relationships

between variables. On the other hand, experimental method is a scientific technique that

involves a sequence of procedures which include observation, identification of a problem,

hypothesis formulation, experimentation, analysis of data, and then the outcome or result

that involves acceptance, rejection, or modification of a hypothesis. One of the

disadvantages of co relational
Moreover, there are very many areas of human life

which cannot be studied using the experimental method because it would be simply too

unethical to do so.

There are three possible results of a co relational study; a positive correlation, a negative

correlation, and no correlation. Positive correlations could be found when either variables

increase or decrease at the same time. Whereas, negative correlations indicates that as the

amount of one variable increases, the other decreases or vice versa. While, no

correlation refers to a condition when there is no relationship between the two variables.

On the other hand, in an experimental method, independent variable is a manipulated

variable in an experiment whose presence or degree determines the change in the

behaviour of the participant or dependant variable. A dependant variable is an observed

variable in an experiment whose changes are determined by the presence or degree of
First of all,

it is essential that the prospective mother receives good medical care and adequate

nutrition, during her pregnancy. The prospective parents should keep their baby in a

smoke free environment. A mother who smokes during pregnancy, as well as second-

hand smoke, are factors linked to SIDS. Although it has been observed that SIDS occurs

mostly in winters, however, do not let your baby get too hot, avoid using too many

blankets. The temperature in your child's room should be comfortable for you. It is

important to know that babies do not need a warmer environment than adults. Put your

baby to sleep on a firm mattress, without thick blankets. Do not put stuffed animal toys or

pillows in your baby’s crib. Avoid puffy under padding such as lambskin or quilts. Do not

put your baby on a waterbed or air mattress. Do not let the baby sleep in your bed, for risk

of accidental smothering and suffocation. The baby should sleep in a crib in the same

room as its parents or caregivers. Never let your baby's face be covered by bedclothes.

Try not to let your baby sleep on the stomach or side. Put the baby to sleep on his or
