You mean data are plural.

"One is my name. The other is not."

I say data because it makes more sense than saying data.

Datums

I say it like dahtay and you can't stop me

Screw both options. Instead I say data.

Me who says it as daetae

I have a French accent so I say data.

Obviously the bottom one is English, and the top one is simplified English.

Sometimes I go both ways ( ͡° ͜ʖ ͡°)

I worked with some Americans who said "these data" all the time. Even though it was technically correct it sounded so grating I wanted to kill them. Everyone other employee from literally every other country would say "this data" barring those smug fucks from Seattle.

I say data (dah-ta) when it is information that cannot normally be read by a human, and data (day-ta) when it is information that has been compiled about a topic that is in human readable format.

"The data on the hard drive has been corrupted." - dah-ta

"The data shows that you have a life expectancy of 78 years" -day-ta

Data’s

It's a noncount noun.

Even people who pretend to believe it's a count noun never use the singular, "a datum".

day-ta da-ta which one is which

Don’t make me bring back Gates Mcfadden. I will turn this star ship around!

I say data when I want to sound sophisticated.

So it’s Lt. Commander….
