Baris ka-1: Dina [[statistik]], '''null hypothesis''' nyaeta hipotesis nu mibanda anggapan awal bener lamun kajadian statistik dina bentuk tes hipotesis nunjukkeun sabalikna. It is a hypothesis that you are interested in showing to be false! Often it is a statement about a [[parameter]] that is a property of a population, the whole population being unobservable, and the test being based on a random sample from the population. Such a parameter is often a mean or a standard deviation. Not unusually, such a hypothesis states that the [[parameter]]s, or mathematical characteristics, of two or more [[~~statistical~~populasi ~~population~~statistik\|~~population~~populasi]]s are identical. For example, if we want to compare the test scores of two random [[statistical sample\|sample]]s of men and women, the null hypothesis would be that the mean score in the male population from which the first sample was drawn was the same as the mean score in the female population from which the second sample was drawn: :<math>H_0: \mu_1 = \mu_2</math>
