The aim of the present study was to investigate seventh grade students’ level of understanding in the statistical investigation process when they are given real data sets. More specifically, seventh grade students’ level of understanding in all the components of the statistical investigation process, which are posing a statistical investigation question, collecting data, analyzing data, and interpreting results. The participants of the study were 121 seventh grade students from one public middle school. Data was collected via the Statistical Investigation Process Questionnaire (SIPQ) during the spring semester of the 2017-2018 academic year. To address the research questions, students' answers were analyzed through the item based in-depth analysis. The findings of the study revealed that levels of understanding of the students were generally high in posing a statistical investigation question. Similarly, students’ levels of understanding were the highest in posing a survey question, but their levels of understanding were the lowest in deciding on the data sources. On the other hand, students’ levels of understanding in analyzing data were low. In other words, students had difficulty in choosing a graph suitable for both data type and the aim of the given scenarios like comparing two different data sets. Besides, the graphs of students were problematic in terms of their structural features such as labeling the coordinates, numerating the axes and connecting paired orders with lines. The findings further indicated that students’ levels of understanding were at intermediate level and advanced level while interpreting results. In other words, students integrated the presented information or they extended, predicted or inferred from the presented information.
