The data set

the data set that we are going to use in this research paper is based on a survey of 116 'young' people that smoke and considers variables related to their intention to stop smoking. The total number of variables in this study are 28.

These variables have information regarding demographic factors, ratings on visual analogues scales (perceived risk, self efficacy, subjective norms and intentions to stop smoking), information on previous smoking related illnesses, health value ratings and 18 items from a reliable and valid questionnaire.

Mean and st.dev of smoking related illness is mean=.49 and st.dev=.502. we run a t test for examine the association among the two variables (smoking related illness and age group) value of t calculated is = 10.540 and 56.612 df = 115 and 115 simultaneousely.

=> "smoking related illness ever" in "no of cigarettes"
