CONCLUSION AND DISCUSSION<br />

Figure 8. Different answers that divide data into five equal parts.<br />

Analysis of the histogram related content knowledge item revealed that most Turkish preservice mathematics<br />

teachers, who subject to teach histogram to middle school students, couldn’t construct a histogram and some of<br />

them have clear misconceptions for histogram concept. However, this result does not conflict with results<br />

reported for other nations (Bruno & Espinel, 2009; Lee & Meletiou-Mavrotheris, 2003).<br />
