UPDATE
A p-value 0.50 from a Spearman Correlation Coefficient
would indicate that there is... - ....ANSWER...Not a
statistically significant relationship between the variables.
An analysis of variance results in a p-value of 0.50. The
researcher should conclude that... - ....ANSWER...There is
not a statistically significant difference between the groups.
True or false: The interpretation of a p-value varies
depends on what statistical test was used to obtain the p-
value. - ....ANSWER...False
