For instance, consider the grouped days-to-maturity data given in Table 2.10(b) on page 57.

From that table, we see that the cumulative frequency of investments with a maturity period of less than 50day is 4(3+1)and, therefore, the cumulative relative frequency is0.1(4/40).

Table 2.14shows all cumulative information for the days-to-maturity data.

Cumulative information for days-to-maturity data.

a. Round each observation to the nearest year and then construct a stem-and-leaf diagram of the rounded data.

b. Truncate each observation by dropping the decimal part, and then construct a stem-and-leaf diagram of the truncated data.

c. Compare the stem-and-leaf diagrams that you obtained in parts (a) and (b).
