If the researcher is reporting that scores are higher than the mean in the population with a p-value of .05, this means that they are reporting the results of a hypothesis test. The incorrectly reported value must be either the p-value or the test statistic, as these are the two values that are directly calculated from the sample data and used to make a decision about the null hypothesis. The effect size (d = 0.14) and the alpha level (.05) are not directly calculated from the sample data, so these values are less likely to be incorrect.
