Dividend Yield
The S&P 500 is an index, you can't buy shares of an index, but you can find index funds to invest in. Each company in that fund that pays dividends will do so on their own schedule, and the fund you've invested in will either distribute dividends or accumulate them (re-invest), this is pre-defined, not something they'd decide quarter to quarter. If the fund distributes dividends, they will likely combine the dividends they receive and distribute to you quarterly.  The value you've referenced represents the total annual dividend across the index, dividend yield for S&P500 is currently ~1.9%, so if you invested $10,000 a year ago in a fund that matched the S&P 500, you'd have ~$190 in dividend yield.
