21. Which of the following statements best describes the utility of biostatistics in research and healthcare? a) Biostatistics primarily focuses on identifying genetic mutations in individuals. b) Biostatistics involves the application of statistical methods to analyze and interpret data in biological an health-related fields. c) Biostatistics is solely concerned with conducting clinical trials for new pharmaceuticals. d) Biostatistics is used exclusively for studying animal populations in ecology. Q2. Which of the following best distinguishes discrete statistics from inferential statistics? a) Discrete statistics involve analyzing continuous data , while inferential statistics focus on categorical data. b) Discrete statistics deal with individual data points ,while inferential statistics make predictions or inferences about populations based on sample data. c) Discrete statistics are concerned with summarizing data using measures of central tendency, where inferential statistics involve hypothesis testing. d) Discrete statistics are used for descriptive purposes only, while inferential statistics are used for m decisions and drawing conclusions beyond the data at hand.

21. The correct answer is b) Biostatistics involves the application of statistical methods to analyze and interpret data in biological and health-related fields.<br /><br />Biostatistics is a branch of statistics that applies statistical methods and techniques to analyze and interpret data in biological and health-related fields. It is used to study the distribution and determinants of health-related events, to evaluate the effectiveness of interventions, and to make informed decisions in healthcare and research.<br /><br />Biostatistics is not solely focused on identifying genetic mutations (option a), conducting clinical trials (option c), or studying animal populations in ecology (option d). It encompasses a wide range of applications and methods to analyze data in various biological and health-related contexts.<br /><br />Q2. The correct answer is b) Discrete statistics deal with individual data points, while inferential statistics make predictions or inferences about populations based on sample data.<br /><br />Discrete statistics and inferential statistics are two different branches of statistics that serve different purposes.<br /><br />Discrete statistics deals with individual data points and focuses on summarizing and describing the characteristics of a dataset. It involves measures of central tendency, dispersion, and position, as well as graphical representations of data.<br /><br />Inferential statistics, on the other hand, is concerned with making predictions or inferences about a population based on a sample of data. It involves hypothesis testing, estimation, and confidence intervals to draw conclusions about the population from the sample data.<br /><br />Option a) is incorrect because discrete statistics can involve both continuous and categorical data. Option c) is incorrect because both discrete and inferential statistics can involve measures of central tendency. Option d) is incorrect because discrete statistics can be used for both descriptive and inferential purposes.
