3.2 Hypothesis Testing The statistical hypothesis is:
Ho: There is no difference in the learning outcomes of fifth grade students in the material of human respiratory organs
using guided inquiry learning model assisted by puzzle picture with conventional learning.
Ha: There are differences in the learning outcomes of fifth grade students in the material of human respiratory organs
using the guided inquiry learning model with the help of a puzzle picture with conventional learning.
The results of the t-test for the hypothesis are:

Based on the calculations in the t-test table, hypothesis 2 shows: the average value for the two classes there is a
difference in the statistical group. The Puzzle Assisted Guided Inquiry class is 82.48, while the control class is 63.50. t
count is 6.154 while t table with df = 39 is 2.0277 then t count > t table or 6.154 > 2.0277. Because t count > t table, then
H0 is rejected and Ha is accepted. it means that there are differences in the learning outcomes of class V students in the
material of human respiratory organs using guided inquiry learning models assisted by puzzle pictures with conventional
learning.
