Overall, women used a slightly higher number of tag Questions: Out of the weighted 5E() tag Questions, men used 'l37 tag Questions (43.1%) and women used 313 tag questions (56.9%). Among men, the number of tag questions increased with age while the number of tag questions decreased with age among women. The women in the 18-25 and 26-45 age brackets used more tag Questions than the men in the same age brackets. But the women older than 45 used fewer tag Questions than the men older than 45. Women with a secondary education used more tag Questions than men with the same education. But both women and men with a tertiary education had about the same frequency of use of tag Questions. 1n the private situations women used more tag Questions than men while in the public situations men used more tag Questions than women
