P, which means difference, should be capitalized and italicized. Mainly to distinguish it from P (phosphorus) and P (power). In addition, in statistical interpretation, generally do not look at the F value, only need to look at the P value. But when writing a paper, you should write out the F value and put the P value in brackets.

Matters needing attention in writing a paper:

Rigorous structure, concise expression and exact semantics. What to write first, then what to write, should be arranged in logical order. Sentences should be coherent and echo each other. Use long sentences with caution and keep them as simple as possible. Every sentence should be clear, and there should be no vague, general or vague words, but the abstract is a complete essay after all, and telegraph writing is not enough.
