Hypothesis


 * Hypothesis**


 * A good hypothesis takes a general problem question and changes it into a form that you can test and research.**

Example: I wonder if students attend a year-round school will their math performance increase?

Students who attend a year-round school will perform better in their math class than their counterparts who attend a traditional school year.


 * Null Hypothesis**


 * It represents no relationship between variables that are being studied.**


 * Acts as a starting point and a benchmark against other outcomes of a study to measure against.**

//"Until you prove that there is a difference you have to assume there is no difference.//"

Example: There will be no difference in math performance between students in a year-round school and those in a traditional school.


 * Research Hypothesis**
 * Statement of relationship between two variables, they are statements of inequality: Directional and nondirectional**
 * Nondirectional-the difference between two groups is not specified**

Example: Students who attend a year-round school perform differently in their math class than their counterparts who attend a traditional school year.

Example: Students who attend a year-round school perform better in their math class than their counterparts who attend a traditional school year.
 * Directional-reflects a difference between two groups and specifically states the difference (greater than, outperforms, less frequently)**

Differences between the Null and the Research Hypothesis: Null stresses no relationship; Research stresses some sort of relationship Null refers to the entire population; Research refers to a sample of the population Null must be indirectly tested and inferred; Research may directly test variable.
