not otherwise....split half method is one way of determining reliability of your test and Spearman-Brown formula is a technique used to re-calculate the correlation of your test when you split your test items into half.... this means that the result of Spearman-Brown provides you the correlation of your test in full length.

If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.

The factor that distinguishes the experimental group from the control group is that the experimental group is subjected to the experimental treatment or intervention being studied, while the control group does not receive this treatment and is used as a baseline for comparison.

The advantage of the correlational research method is the ability to prove a positive or negative correlation between two subjects . The disadvantage of this is the unclear interpreation of cause and affect. moletsane

which analysis method cannot be applied to experimental research

The experimental method allows researchers to establish cause-and-effect relationships by manipulating variables and controlling for confounding factors. This method provides more control over the research setting, increasing internal validity compared to non-experimental methods.

Experimental Method

While the experimental method is ideal for determining cause and effect, the correlational method is still valuable for studying relationships between variables when it's not feasible or ethical to manipulate them. Correlational studies can provide useful information about associations between variables and generate hypotheses for further experimental research.

The correlation method examines the relationship between two variables without manipulating them, while the experimental method involves manipulating one variable to observe its effect on another. Correlation does not imply causation, whereas experimental research can establish cause-and-effect relationships. Experimental research allows for greater control over variables compared to correlational studies, making it better suited for establishing causality.
