 that EFL learners’ expository text comprehension across three proficiency levels can be significantly predicted by their use of reading strategies. Accordingly, the ninth null hypothesis of the study was rejected.
In order to test the tenth research hypothesis of the study in finding whether beginner EFL learners’ use of reading strategies can be a significant predictor of their comprehension of expository text, another multiple regression analysis was performed.

The F value in the Table 4.21 showed that (F(1,42) = 8.87, p .05). as can be seen p value is lower than assumed level of significance therefore, beginner EFL learners’ use of reading strategies can be considered as a significant predictor of their comprehension of expository text (i.e., the regression model is a suitable for the data). Therefore, the tenth null hypothesis of the study was rejected.
In order to test the 11th research hypothesis of the study in finding whether intermediate EFL learners’ use of reading strategies a significant predictor of their comprehension of expository text, another multiple regression analysis was performed.

The Table 4.23 showed that (F(1,49) = 8.03, p .05). As can be seen, p value is lower than the assumed level of significance; therefore, intermediate EFL learners’ use of reading strategies is a significant predictor of their comprehension of expository text i.e., the regression model is a suitable for the data. Therefore, the eleventh null hypothesis of the study was also rejected.
In order to test the 12th research hypothesis of the study in finding whether advanced EFL learners’ use of reading strategies is a significant predictor of their comprehension of expository text, a multiple regression analysis was performed.

As shown in Table 4.24, the coefficient of multiple correlations R is the measure of the prediction of the dependent variable; in this case, comprehension of expository texts by advance learners. A value of 0.577 indicates a good level of prediction. The R2 value indicates that 33% of the variability of the expository text comprehension of advanced EFL learners’ is explained by the use of reading strategies.

The F value in the Table 4.25 showed that (F(1,23) = 6.70, p .05) showing that the advanced EFL learners’ use of reading strategies is indeed a significant predictor of their comprehension of expository text and that the regression model is a suitable for the data. Therefore, the twelfth null hypothesis of the study was rejected.
In order to test the 13th research hypothesis of the study in finding whether EFL learners’ use of reading strategies is a significant predictor of their comprehension of argumentative text across different proficiency levels, a multiple regression analysis was performed. Table 4.26 provides the extent to which variability in the dependent variable variables (argumentative text comprehension across three proficiency levels) is accounted for by the independent variable (reading strategies use).

The F value in the Table 4.27 shows the fitness of overall regression model for the data. The results showed that (F(1,118) = 4.93, p .05). As show in the Table above, p value is lower than the level of significance therefore, the EFL learners’ argumentative text comprehension across three proficiency levels can be significantly predicted by their use of reading strategies. Therefore, the thirteenth null hypothesis of the study was not accepted.
