Other projects like AgeGuess [8] focus on the senior demographics and enable the elderly to upload photos of themselves so the public can guess different ages. Lists of citizen science projects may change. For example, the Old Weather project website indicates that as of January 10, 2015, 51% of the logs were completed. [9]
The use of a sequence of experiments, where the design of each may depend on the results of previous experiments, including the possible decision to stop experimenting, is within the scope of sequential analysis, a field that was pioneered [13] by Abraham Wald in the context of sequential tests of statistical hypotheses. [14]
The Principles and Standards for School Mathematics was developed by the NCTM. The NCTM's stated intent was to improve mathematics education.

As a result of this controversy, and despite the ongoing influence of the New Math, the phrase "new math" was often used to describe any short-lived fad that quickly becomes discredited [citation needed] until around the turn of the millennium [7] [better source needed]. In 1999, Time placed it on a list of the 100 worst ideas of the 20th century.
