Two-alternative forced choice (2AFC) is a method for measuring the sensitivity of a person or animal to some particular sensory input, stimulus, through that observer's pattern of choices and response times to two versions of the sensory input.
Another refinement of the slimline PlayStation 2 (SCPH-9000x) was released in Japan on November 22, 2007. [8] As well as some cosmetic changes, the design of the hardware was overhauled, incorporating the power supply into the console itself like the original (fat) PlayStation 2 revisions; this also increases the total weight to 720 grams (25 oz).

Bias level for each type was set equal to the optimal bias of the relevant IEC reference tape, and sometimes changed when the IEC changed the reference tapes, though the BASF datasheet for the Y348M tape, approved as the IEC Type I reference in 1994, says that its optimal bias is exactly 0.0 dB from the previous reference (BASF R723DG).
By matching treated units to similar non-treated units, matching enables a comparison of outcomes among treated and non-treated units to estimate the effect of the treatment reducing bias due to confounding. [1] [2] [3] Propensity score matching, an early matching technique, was developed as part of the Rubin causal model, [4] but has been ...

Otero sees the Media Bias Chart as an "anchor" that counteracts political polarization in news media, and aspires for Ad Fontes to become a "Consumer Reports for media ratings". [5] She compared low-quality news sources to junk food, [12] and described sources with extreme bias as "very toxic and damaging to the country". [4]
