Reports in psychology journals almost always include the statement, "Results were statistically significant.". Explain what this means regarding an experiment, and describe how these findings can become even more convincing
What will be an ideal response?
After conducting an experiment, you compare the scores (dependent variable) obtained by the experimental group to those obtained by the control group. If you find a difference, then you must use statistics in order to tell if the independent variable really made the difference or if the difference occurred by chance. Thus, the phrase "Results were statistically significant" means that the obtained results would have occurred very rarely by chance alone. To be statistically significant, a difference must be large enough that it would occur by chance in less than five experiments out of 100 . Of course, findings also become more convincing when they can be replicated
