While reading SICP, if found the following expression:

Since the Fermat test has O(log n) growth, how would you expect the time to test primes near 1,000,000 to compare with the time needed to test primes near 1000? Do your data bear this out?

Is it correct? Shoudn't it be "Does your data bear this out?"

Data is a plural noun as indicated here. As such it takes the plural verb form do rather than the singular form does.

However, common usage often treats it as singular. This ngram reflects a significant usage of the singular, although the plural still is favored.

While "data" is plural (the singular is datum), it can be used as either a count noun or a mass noun. Since this particular instance is referring to two types of data (the time to test primes near 1,000,000 and the time needed to test primes near 1000), my guess would be to use data as a count noun, in which case "do your data" would be correct.
