Chapter 2 Descriptive Statistics Download Free Pdf Quantile Histogram Chapter 2 descriptive statistics free download as pdf file (.pdf), text file (.txt) or read online for free. the document discusses graphical analysis tools for summarizing data, including histograms. Histogram a graph consisting of bars of equal width drawn adjacent (they touch) to each other. the horizontal scale represents classes of quantitative data values and the vertical scale represents frequencies.
Statistics Chapter Ii Pdf Histogram Pie Chart Describing the spread of the data range: [min(x); max(x)] quantile (quartile, quintile, percentile, etc.): 25 percentile = lower quartile 50 percentile = median 75 percentile = upper quartile interquartile range (iqr): a measure of variability. In this chapter, we will briefly look at stem and leaf plots, line graphs, and bar graphs, as well as frequency polygons, and time series graphs. our emphasis will be on histograms and box plots. Graphical representations for quantitative data histogram – like a bar chart, but the bars touch (start the vertical axis at 0). In this chapter, you will study numerical and graphical ways to describe and display your data. this area of statistics is called "descriptive statistics". you will learn to calculate, and even more importantly, to interpret these measurements and graphs.

Note: in this class we will use intervals of equal width, as shown in the table and in the histogram; although unequal intervals can be used in some situations, the statistical work is easier if the intervals have equal width. descriptive statistics notes, by roberta bloom de anza college. This says that we estimate that at least 99.73% of the parts will be inside the specifications—that is, between 2.97 and 3.03. therefore, the process is capable. The first quartile (q 1 ) is the 25th percentile,the second quartile (q 2 or median) is 50 th percentile, and the third quartile (q 3 ) is the the 75 th percentile. the interquartile range, or iqr, is the range of the middle 50 percent of the data values. the iqr is found by subtracting q 1 from q 3 , and can help determine.
