In calculating a one-sample chi-square test,if you had 7 degrees of freedom,your variable would have ______ categories.

The most commonly used nonparametric test is the ______.

Which of the following nonparametric tests is used to answer the following research question: "Is preschool twice as effective as no preschool experience for helping develop children's language skills?"

Which of the following is the symbol for summation?

In the result χ²₍₅₎ = 9.4,p < 0.05,what is 5?

Write a sample research question where the Kolmogorov-Smirnov test would be the most appropriate statistical technique to use.

If there are six categories for which you are calculating a one-sample chi-square,what are the degrees of freedom?

In the result X²₍₃₎= 8.4,p < 0.05,what is 8.4?

In the result χ²₍₅₎ = 9.4,p < 0.05,what is χ²?

Statisticians have found that it takes a sample size of about _____ to fulfill the assumption of parametric statistics that the sample is large enough to represent the population.

Which of the following nonparametric tests is used to answer the following research question: "What is the exact likelihood of getting six heads on a toss of six coins?"

When conducting a chi-square test,the categories of your variable(s)must be ______.

In a one-sample chi-square test,if your respondents are distributed very unequally across the levels of your variable,your chi-square value will be ______.

In the chi-square test for independence,expected values and observed values are used,just like in the chi-square goodness-of-fit test.The difference is that in the test of independence,there are three dimensions involved,instead of one.

How do you interpret X²₍₃₎= 18.9,p < 0.05?

The obtained value must be compared against which of the following?
