What is the difference between analyses and analysis?

If you’re conducting a highly detailed examination of something, you’re completing an analysis. The word analysis is a singular noun, so if you’re running more than one analysis, the correct plural form is analyses

The noun’s tricky singular and plural forms are made more confusing by British and American spelling variants. In the United States, English speakers use the verb “analyze,” while British English speakers spell the word as “analyse.”

English speakers pronounce the nouns analysis as “an-al-lye-sis,” analyses as “an-al-lye-seez” (four syllables each). In contrast, we pronounce the verb analyse or analyze as “an-al-lyez” (three syllables).
