- 13. Variability and inferential statistics Two researchers, Dr. Kim and Dr. William, are studying the relationship between how many minutes per day a child spends on a computer and how many words per minute the child can type. Each researcher compares two samples of 50 fifth grade students. One sample spends less time on a computer, the other spends more time. The following table shows the mean and standard deviations of words per minute the child can type, as they might be shown in a journal article. Researcher: Dr. Kim who: Researcher: Dr. William Sample A Spends less than 15 minutes on a computer per day (M = 22.16, SD = 10.06) Spends 15-30 minutes on a computer per day (M = 24.66, SD = 8.79) Sample B Spends more than 15 minutes on a computer per day (M = 28.34, SD = 11.12) The summary data from study demonstrates a stronger relationship between how many minutes per day a child spends on a computer and how many words per minute the child can type. (Hint: Consider the magnitude of…I. Write True if the statement is Correct and False if the statement is wrong. 1. Qualitative data uses non-parametric statistics. 2. Ordinal data can be stored in the computer. 3. Ranking is the appropriate operating for ordinal scale. 4. Hypothesis testing is an inferential statistics. 5. Estimation is a descriptive statistics.If we can perform a census (i.e. collect data from the entire population), then we can forget about inferential statistics. Can you recall or think of at least one reason why we might choose to collect a sample instead of perform a census when studying a population?
- Which of the following is not true about the process of statistics? Question content area bottom Part 1 Choose the correct answer below. A. When the results from a sample are extended to the population, it is called inference. B. If data are not collected properly, the conclusions that are drawn will be meaningless. C. Data are typically collected from a sample because it is too difficult and expensive to collect data from an entire population. D. The first step in the process of statistics is to collect the data.13 Descriptive statistics consists of methods for organizing, displaying, and describing data by using tables, graphs, and summary measures. Select one: True False1. true or false. In most situations in the “real word”, we know the value of the population proportion. A. True B. False 2. True or False. Statistics inference is the art and science of drawing conclusions about a population on the basis of observing only a small subject of that population. A. True B. False
