For a variety of reasons, many scientists recommend that instead of (or in addition to) stating the p value, researchers should show the means and:
A) the mode for each group.
B) 95% confidence intervals for each group.
C) 85% confidence intervals for each group.
D) the median for each group.
P Value
A statistical measure that indicates the probability of the observed data occurring under the null hypothesis, used in hypothesis testing to determine significance.
95% Confidence Intervals
Statistical ranges, with a 95% surety, where the true value of a parameter, like a mean, is expected to lie.
Means
Methods or resources available to accomplish an end or to achieve a desired outcome.
- Understand the relevance of confidence intervals in complementing p-value findings for more robust research insights.

Final Answer :
B
Explanation :
Showing 95% confidence intervals for each group provides a more informative measure of the magnitude and precision of the effect size compared to simply stating the p value. Confidence intervals also provide information about the range of possible values for the true population parameter, which is more meaningful for practical applications. The other options (A, C, D) do not provide as much useful information as confidence intervals.
