Some politicians say the entire 54th Assembly District, which passes through six neighborhoods, has the same difficulty.
Table 4 displays the output for the hypothesis that the item has the same difficulty across two groups (statistically significant differences only).
Three hypotheses will be tested: the first hypothesis is that the item has the same difficulty across two groups, the second is that the item has the same difficulty as the average difficulty for all groups, and the third hypothesis is that the item has no overall DIF across all groups (Linacre, 2004).
However, as pointed out in [1], the ideal form of the method is often impractical since, in many cases, to solve the problem (1.2) exactly is either impossible or has the same difficulty as the original problem (1.1).
Unfortunately, we do not know the value of the constant t at all, and how to find the value of t has the same difficulty as solving the original problem.
For the hypothesis that the item has the same difficulty as its average difficulty for all groups, statistically significant differences at an alpha level of 0.05 are shown below in Table 3 (a total of 6 items as follows: 5, 17, 23, 29, 41, 49).
We found that as we got to know each other, although we had grown up in France 300 miles apart, we'd had the same difficulties as children.
His deputy, Anne Krueger, was more discouraging, saying, "We are not going to be able to lend into a situation where they continue having the same difficulties".
The minister of higher education, Valérie Pécresse, argued that French who grow up in a poor neighborhood have the same difficulties regardless of ethnicity.
In accepting the Nobel Peace Prize in 1979, Mother Teresa said, "I always wonder that 400 to 500 years ago as St. Francis of Assisi composed this prayer, that they had the same difficulties that we have today".
