1. A data file contains the following data, five households do not have cars, 20 households own a car of ten households have two cars, pointing out which of the following statistics are used to describe the data and calculate the statistics value. (B) has a median number of cars.
2. In order to generate the sum of a given variable, which should choose a summary statistic (A) mean
3. Suppose data. FIG 3-45, the mean ABC if necessary to obtain these three variables, and the desired value in the case of using the missing information has been possible to obtain average data, select which function can be achieved in SPSS Claim. (B) mean.2 (abc)
5 mean average fair comparison, the number is a number taken up, the median is the middle number is taken.
6 is very similar to bar graphs and histograms, application and performance data on a continuous pattern without any spacing between each square bars histogram, the histogram data is first divided into several continuous consecutive intervals, and the observation value calculated fall within the frequency or the relative frequency of each interval. From the histogram can be visually observed data distribution.
FIG stem quantitative variables describing a graphical manner, it can be given in addition to histogram distribution information given, it also is possible to restore most of the original information data
If you want to show information of the original data as possible should be used leaf map
7. FIG Pareto chart is a special tone rectangle formed after adjustment in descending order of the bar graph.
Very similar histograms and bar charts, the data applied to the continuous sheet, without any spacing between the histogram and the respective square bar pattern now.
8. noted that indicators which measure of central tendency is used to describe the following attributes, if there are two or more indicators can, please indicate which indicators may reflect the most amount of information? (B) driving the car type.
9. For the four variables on the question, they were in what may be described in the following graphics? (C) Pareto FIG.
