Document Summary

There was a study that was done by matias mehl about sex difference in talkativeness. It was stated that women spoke more than men per day. They concluded that there was no evidence from the population of sex difference in talkativeness from their sample. There was also another study by allen kanner and his colleague about daily hassles and symptoms. It was concluded from the researchers that there"s a relationship of symptoms and hassles from the population. There is a technique called inferential statistic, which helps researchers with their sample result reflecting when there is true of the population. In the approach, there is also null hypothesis testing. This is where conclusion would be drawn between the mean and about the correlation of variable. In a research, usually it involves measuring a few variables. The main goal in researching is to use sample statistic to draw conclusion based on the value for the population.
