Table 1 presents mean values (M) and standard deviations (SD) for all the variables investigated for comprehensibility ratings for the whole group (N = 80). As can be seen from the data, the mean for sentence stress was the highest (M = 31.44), followed by vowel and word stress (M = 30.35 and M = 28.32). The mean for consonant was the lowest (M = 19.99). This means that sentence stress contributed significantly to the ratings of comprehensibility and consonant errors did not correlate much to the L2 comprehension.
