1. A class of 20 students received the following scores on a math test: 85, 72, 90, 78, 92, 85, 65, 88, 72, 95, 80, 75, 85, 90, 70, 82, 85, 78, 90, 85. Construct a frequency distribution table for this data using intervals of 5 (e.g., 65-69, 70-74, etc.).
2. What type of frequency indicates the number of observations within a specific class interval?
Relative frequency
Cumulative frequency
Absolute frequency
Frequency distribution
3. If a dataset has 50 observations and 10 of them fall into a specific class interval, what is the relative frequency for that interval?
10
0.20
50
5
4. The sum of all frequencies in a frequency distribution table should always equal the of observations in the dataset.
5. A frequency distribution shows the total number of observations that fall below the upper boundary of each class interval.
6. A survey was conducted to find out the number of hours students spend studying per week. The results are summarized in the cumulative frequency table below: Hours Studied | Cumulative Frequency --------------|--------------------- 0-5 | 5 6-10 | 12 11-15 | 20 16-20 | 25 How many students study between 6 and 10 hours per week?
7. Observe the bar graph below, which represents the number of books read by students in a month.
a) Which class read the most books?
b) What is the total number of books read by Class A and Class C combined?
8. A histogram is a graphical representation of a frequency distribution.
True
False
9. In a grouped frequency distribution, the sum of the relative frequencies is always equal to 1.
True
False
