Rather than calculate the number of tomatoes per quart or pint, I find it more helpful to judge by the batch. We have been canning tomatoes (whole) for more than 20 years, and by now I know that 2 five-gallon buckets of our Viva Italia tomatoes gives us about 3 pressure canner's worth (21 quarts). That way I have some idea of how many jars and lids and time I need for a canning session.
History of IQ Tests. Technically speaking, the first IQ test was developed by French psychologist, Alfred Binet in 1905. His test has provided the base for all modern IQ tests that are widely used today. However, the interest of scientists and psychologists in intelligence dates back to thousands of years.
The test is scored in terms of intelligence quotient, or IQ, a concept first suggested by German psychologist William Stern and adopted by Lewis Terman in the Stanford-Binet Scale. The IQ was originally computed as the ratio of a personâs mental age to his chronological (physical) age, multiplied by 100.
