pls answer this

Question 2 point (graded) 0/1 Assume you are a test-maker comparing a set of questions which all have the same guessing level (so c is .constant) ? How, if at all, does the parameter a help you determine the discrimination level of a question The parameter a has no effect on the discrimination value of a question because the location of the a inflection point of P (0) is independent of Smaller values of a correspond to shallower slopes at the inflection point, so students with very different ability levels still have similar probabilities of answering correctly Smaller values of a correspond to shallower slopes at the inflection point, which makes it easier to distinguish between students with different ability levels around the location of the inflection point Very large values of a correspond to steeper slopes at the inflection point, which makes it easier to distinguish between students with different ability levels around the location of the inflection point The smaller the value of a is, the harder it is to use test results to distinguish student ability levels at .the inflection point The larger the value of a the easier it is to distinguish between students with different ability levels, .no matter where on the ability spectrum they are .None of the above
