Two questions about my study

[anoopbal]

I have 2 questions about my study:

1. I did a study but now I have only one male and the rest are females. I have like 19 sample size. So should I exclude the male subject or keep him and use an ANCOVA?

2. When i use an ANCOVA, I get the means and SE from SPSS, but no SD. Can I use that SE to calculate the SD to get the effect sizes?

thank you so much

1. that really depends on the situation; nobody can say in generality with this limited info.
2. yes. but SE is the SD of the coefficients, so use SE for CI on coefficients, etc.; this might be helpful
