A point estimate is a summary statistic from a sample that is just one number used as an estimate of the population parameter.
Statistical power is a measure of the likelihood that we will reject the null hypothesis, given that the null hypothesis is false.
A meta-analysis is a study that involves the calculation of a mean effect size from the individual effect sizes of many studies.
A confidence interval is an interval estimate based on a sample statistic; it includes the population mean a certain percentage of the time if the same population is sampled from repeatedly.
Cohen's d is a measure of effect size that assesses the difference between two means in terms of standard deviation, not standard error.
An interval estimate is based on a sample statistic and provides a range of plausible values for the population parameter.
Effect size indicates the size of a difference and is unaffected by sample size.
