The writer calculated the data to find out the result. This data was the basic consideration in designing the materials. In order to gain the information, the
writer also interpreted the result of the interview with the homestay hosts.
2. Evaluation on the Design
The data for the evaluation were divided into two categories. The first category was about the respondents’ opinions that were shown statically. The
second category was the respondents’ comments and suggestions that were explained in sentences.
a. Descriptive Statistics of Respondents’ Opinion on the Designed Materials
In this study, the writer calculated the data from materials evaluation questionnaire using central tendency proposed by Brown and Roger, namely,
“mean” Brown and Rodger, 2004: 128. The mean was to describe the average performance among a group of scores. The mean or average point was obtained
by calculating the sum of the respondents’ answer ∑ x divided by the numbers
of respondents N. The formula was:
N x
X
∑
=
PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI

Note: X : The average point
∑ x : The sum of respondents’ answer N : The number of the score
The assessment of the respondents’ opinion of the designed materials used five points of agreement. They are described in the table below.
Points of Agreements Score
Strongly disagree 1
Disagree 2 Uncertain
3 Agree 4
Strongly agree 5
Table: 3.3. Point of Agreements
The data presented in the form of the table were the respondents’ opinion, statements, and the mean. The form of the results of the materials evaluation
questionnaire was presented in the following table.

The data from the evaluation would show whether the designed materials were acceptable or not. In order to know whether the designed materials were
acceptable or not, the writer gave description to categorize the result. The maximum points were five. The designed materials were considered good and
acceptable if the total central tendency was more than seventy-five percent from the maximum points. The materials designed were considered good but needed
crucial revisions if the total tendency was fifty up to seventy-five percent. The materials designed were considered poorly designed if the total of central
tendency was less than fifty percent.
b. Respondents’ Comments and Suggestions
