When using the method of limits to measure a threshold, the crossover point between detecting vs. not-detecting a threshold may be different for ascending and descending trials. (see isle 2.2 to experience method of limits). why do you think this happens? researchers usually average together the results of ascending and descending trials. do you think this is valid? why or why not?

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

only 10/60 isn't equivalent

hope this : )

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
