[求助] Spss 中F括号内是什么意思

As shown in Fig. 2, the duration of swimming time over 20 min of exhaustive swimming was significantly increased in RHO-treated mice, compared with the control group. Analysis of variance confirmed the significant effect of treatment on the swimming time [F(3,28) = 6.937; p < 0.01]. A post-hoc comparison showed a statistically significant effect of RHO following administration of the intermediate dose of 15 mg/kg (p < 0.01), while doses of 10 and 20 mg/kg failed to reach statistical significance (p > 0.05).

这是我在论文中照抄的一段话,请问
[F(3,28) = 6.937; p < 0.01]. 中F括号内的3和28 分别代表什么意思?
要写路嫩,需要用到这样的话,特此求助
