The lexical decision task (LDT) is an experimental paradigm where participants make
word/nonword decisions for letter strings presented on a computer screen. This
experiment as been replicated many times, and the average reaction time for common
monosyllabic words is 710 milliseconds. Dr. Lupker's lab runs a version of the LDT in
which participants simultaneously hear the stimuli pronounced on a set of headphones.
Dr. Lupker hypothesizes that receiving two sources of information will increase
reaction times. 20 people take part in the study. Below are the average response times
(RT) for each person, expressed in milliseconds.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
