if an independent-measures study uses n = 15 participants in each group to compare two treatment conditions. then 28 is the df value for the t statistic for this study.
The t-statistic, which is used in statistics, measures how far a parameter's estimated value deviates from its hypothesised value relative to its standard error. Through the Student's t-test, it is utilised in hypothesis testing. In a t-test, the t-statistic is used to decide whether to accept or reject the null hypothesis. The t-statistic is used when the sample size is small or the population standard deviation is unknown. It is quite similar to the z-score in other respects. Once the standard deviation is unknown, the t-statistic is in use, for one, to approximate the population mean from a sampling distribution of sample statistics.

An agricultural society, also known as an agrarian society, is a society that constructs social order around a reliance upon farming. More than half the people living in that society make their living by farming.
People in an agricultural society generally lead a more settled lifestyle than those in nomadic hunter-gatherer or semi-nomadic pastoral societies because they live permanently near the land that is farmed. Agricultural settlements tend to develop in areas of convenience near bodies of water, which is used for both crops and transportation, or along trade routes. Not everyone in an agricultural society is a farmer. Some people make a living trading or making and selling goods such as tools used for farming.
