✔ 最佳答案
根據以上個圖表,計significant係要用t-test(test有冇correlation)H0: no correlation(correlation=0)
HA: correlation not =0
t=(0.891-0)/standard error
correlation is significant at 0.01 level即係話 |t|>2.575, reject H0
亦可以話當significant level=0.01, 2個variables就有correlation
p.s. H0 null hypothesis, HA alternative hypothesis
