The main focus of descriptive statistics is to summarize and present data. TRUE OR FALSE? 3.Normal curve model can determine the proportion of scores between the mean and a particular score. TRUE OR FALSE? 4. The bar graph is a type of graph in which the classes are marked on the horizontal axis and the frequencies on the vertical axis. It has no existing gaps between columns because the data is continuous. TRUE OR FALSE?5. In a normal distribution, approximately 68% of scores will fall within two (2) standard deviations of the mean. TRUE OR FALSE? 6. In a normal distribution, approximately 99% of scores will fall within three standard deviations of the mean. TRUE OR FALSE? 7. In a normal distribution, approximately 95% of scores will fall within one (1) standard deviation of the mean. TRUE OR FALSE? 8. The median is the most frequent occurring value in the distribution. TRUE OR FALSE? 9. Inferential statistics are used to describe the basic features of data in a study. TRUE OR FALSE? 10.Every set of interval level and ratio level data has a mean. TRUE OR FALSE
