Imagine that you are presenting some research results that show a statistically significant difference in student reading scores when public and private school students are compared, and someone asks you what the meaning of "statistical significance" is. Describe, in non-technical, "layperson's" language, whatstatistical significancemeans. Don't use any statistical or technical language (e.g., "null hypothesis," "standard error", "critical values").

	A	Statistical significance indicates that the difference in mean reading scores between public school students and private school students was due to more than sampling error alone.
	B	Statistical significance indicates that the difference in mean reading scores between public school students and private school students was computed using technical and mathematical techniques, and therefore proves that a difference exists.
	C	Statistical significance indicates that the difference in mean reading scores between public school students and private school students could never occur by chance.
	D	Statistical significance indicates that the difference in mean reading scores between public school students and private school students is large in magnitude.
