Construct a histogram and frequency polygon to display the data
Construct a frequency distrbution to display the data with a class
size of 8 with the lowest value of the data as the starting point
in lowest class limit value.
5 Write a paragraph summarizing the distribution of the data

3. Problem Statement
Twenty-five students completed a questionnaire that measured attitudes toward
interpersonal violence. Respondents who scored high believed that in many situations,
a person could legitimately use physical force against another person. Respondents
who scored low believed that in no situation (or very few situations) could use of
violence be justified.

8. Summary
Therefore, it was shown on the FDT that
majority of the respondents scored between
16-26. Hence, they believed that in no
situation ( or very few situations) could use of
violence be justified.
