1. Data can be specified by using two measures 1) 2) 2. We make inferences about the Population on the basis of information obtain from 3. Two events are said to be if they both cannot occur at the same time. 4. There are total of. possible ways to choose "r" objects out of "n" objects in the sample space. 5. There are total of possible ways to choose "r" ordered objects out of "n" objects in the sample space. 6. Statistics deals with where as probability provides numerical measure for it. 7. is a sub part of population. 8. Mean is Average, where Median is Average. 9. Sum of observation divided by their number is called 10. Any numerical value calculated from population is called, 11. Any numerical value calculated from sample is called. 12. Two events are said to be _if one is as likely to occurs as the other. 13. A probability based on reduced sample space, due to some information come in known, is called 14. We a coin is tossed there are possible outcomes. 15. When a dice is rolled there are possible outcomes. 16. Probability is the. measure of uncertainty. 17. A variable which can take every possible value is called 18. A variable which takes values in jumps is called 19. Sample space is the collection of outcomes of a random experiment.
