Increasing the mean difference between groups will <em>increase </em>the likelihood of finding a significant p value from a t test.
In statistics, in addition to the mode and median, the mean is one of the measures of central tendency. Simply said, the mean is the average of the values in the given collection. It indicates that values in a certain data collection are distributed equally. The three most often employed measures of central tendency are the mean, median, and mode. The total values provided in a datasheet must be added, and the sum must be divided by the total number of values in order to get the mean.
When all of the values are organised in ascending order, the Median is the median value of the provided data. While the number in the list that is repeated a maximum of times is the mode.
