Question

Divides Area in Half 4 The total area in the histogram = boxes Half the area in the histogram- boxes Add a vertical line to the frequency distribution histogram that divides the total area exactly in half. In other words, place the vertical line so that it makes the area on the right and left of the line equal. (Hint: Dragthe line labeled Divides Area in Half onto the graph. First, make sure your line is vertical by positioning its two circle symbols on the same vertical grid line; avoid positioning either circle on the edge of the graph area. Then grab the line by a point that is not one of the circles to slide it to its correct position.) Assume that the scores are measurements of a discrete variable. Find the median The median is Now assume that the scores are measurements of a continuous variable. Find the precise median. The median is

Answer 1

Answer:

From the observed frequency distribution histogram, The total area in the histogram 5 boxes Half the area in the histogram 2.5 boxes. The frequency distribution histogram is as shown in the below: 4 disiuion The vertical line in the above frequency distribution histogram divides the total area exactly in two halves. a o haieit

If the scores are measurements of a discrete variable then, Cumulative XFrequencyfrequency Here, N-5 N 5 Thus,-=-= 2.5 The median is the 3th term, the cumulative frequency with 3 corresponding X value is median The median is2

If the scores are measurements of a continuous variable then, The median can be calculated by using the following table fr 3-4 Here, is 2.5 The value greater than 2.5 in cumulative frequency is 3 and the c is the median class class interval The formula for the median is, Here, L is the lower limit of the median class, F is the cumulative frequency of the preceding median class, fis the frequency of the median class, and h is the class width. The median is, Median L+ (2.5-1),x1 -1+0.75 1.75
