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.
This adapted test, first published in 1916, was called the Stanford-Binet Intelligence Scale and soon became the standard intelligence test used in the U.S. The Stanford-Binet intelligence test used a single number, known as the intelligence quotient (or IQ), to represent an individual's score on the test. This score was calculated by dividing the test taker's mental age by their chronological age, and then multiplying this number by 100. For example, a child with a mental age of 12 and a chronological age of 10 would have an IQ of 120 (12 /10 x 100). The Stanford-Binet remains a popular assessment tool today, despite going through a number of revisions over the years since its inception.
