It is a bar graph which showsfrequencies (axis “y”) of dependent scores (illustrated at “x” axis). In this example “x” valuesrepresents Speed_of_Light (represented in nanoseconds [ns]).Frequency represents the quantity of particular atrribiutes, for example for the range 0-10 [ns] thefrequency is 0, which means no possibility of speed of ligh occurrence at that range. The higestpossible is at range of 20-30 [ns] and is represented in frequency axis at value of about 43.frequency10203040-40-202040Speed_of_Light•Density estimateDensity estimate graph is a different representation of histogram, but represents the data through thebandwidths, which are larger when the point density becomes higher.Density estimations have simmilar problem as histogram - a different kernel may yield a completelydifferent curve. The graph can be over- or undersmoothed, so it is so important to find the optimalvalue of the bandwidth. The smoothing parameter determines the width of the bandwidths.Density0.000.020.040.060.08-40-20Speed_of_Light2040•BoxplotBox plot allows to interprate the distributional characteristics of scores level a group of scoreswhich are divided to four main groups (25% of all scores are placed in each group). The linesdividing the groups are called quartiles, and the groups are referred to as quartile groups.The box plot representation is shown at a graph with few scores characterized below.1. Median – middle point of data set where greater than 50% of data isgrater than this value.For my example median is about 28-29.2. Upper quartile - Seventy-five percent of the scores fall below the upper quartile (value=30).3. Lower quartile - Twenty-five percent of scores fall below the lower quartile (value=25).4. Maximum – Gratest value, excluding outliers (value=40).5. Minimum - Least value, excluding outliers (value=18).6. Outlier – Lessv than 3/2 times of lower quartile (values 0 [50] and -42 [31]).Speed_of_Light204055-40-2031 [ Pobierz całość w formacie PDF ]
