Because statistical software plays such an important role in modern statistical applications,many studies have encouraged the use of technology in statistics courses.The Guidelines for the Assessment and Instruction in Statistics Education (GAISE)(Aliaga et al. ,2005)project was funded by the American Statistical Association to examine needs for college level statistics courses.One of the six recommendations from GAISE is the use of technology for developing conceptual understanding and analyzing data.A survey was sent to students at 100 different universities across the United States to access the relationship between ease of learning the statistical software program SAS and a student's currently level of SAS proficiency.The results of the survey are published in Jackson et al. ,2011,in the International Mathematical Forum journal and are shown below. Table 1.Two-way table for ease of learning SAS and SAS proficiency level. The letters J,K,and L represent the ______ distribution for ease of learning SAS. A)conditional B)marginal C)joint D)$\chi$²

The letters J, K, and L represent the marginal distribution for ease of learning SAS. This means that they represent the frequency distribution of the ease of learning SAS regardless of the SAS proficiency level. The joint distribution would show the frequency distribution of both ease of learning SAS and SAS proficiency level together, and the conditional distribution would show the frequency distribution of ease of learning SAS given a specific SAS proficiency level. However, in this case, the table only shows the frequency distribution of ease of learning SAS and SAS proficiency level separately, so the marginal distribution is the appropriate choice.
