Example sentences for: df

How can you use “df” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • NAD achieved nearly twice the BMI loss as AD and ADSx, at means of 4.0, 2.6 and 2.3 respectively (F = 6.25, df = 2,212, p = 0.002).

  • Gene specific primer sequences, cycle times and annealing temperatures are outlined in Table 1. For each transcript, raw densitometry data was subjected to paired t-testing (two-sided, df = 7) to determine whether differences in expression existed in mefloquine and DMSO-treated cultures ( P < 0.05).

  • Finally, with regard to FSH action, FS has been shown to neutralize the bioactivity of the FSH inhibitor, BMP-15 [ 39 ] . It is possible, therefore, that the strong expression of FS by the DF may serve to modulate BMP-15 action such that sufficient FSH receptors are expressed in the GC to permit the development of a preovulatory follicle.

  • The evolved populations performed nearly equivalently with or without bile salts, relative to the ancestor (1-tailed paired t s = 1.10, df = 11, p = .138).

  • 0 under the alternative non-central t distribution g ( t, df 1 , δ): . Now when the n samples are randomly assigned into pools of size p with equal mixing, power is decreased because the degrees of freedom are reduced to df 2 = 2( n / p - 1), which makes the tails of the central t distribution under H 0 heavier and thus the critical value t 0 * will be further from 0, while the non-centrality parameter is unchanged: (since the variance is reduced to σ 2/ p and the number of chips reduced to n / p ). However, if n + k subjects with pool size p are compared to n subjects without pooling, then the power change is not monotonic.
