Question

5. What type of frequency distribution graph should be used for the variable gender? (5 points) Why would the variable "number of brothers and sisters" be appropriate for construction of a histogram? (5 points) 6. Construct a frequency distribution table for a variable which has the following scores: 5,8,6,10,4, 7,8,6,9,7,9, 10,6, 8, 7,9,5,8,7,9 (15 points) 7. Construct a histogram with the scores from the following variable (15 points) 45-49 40-44 35-39 30-34 25-29 20-24 10 send to tinder Download Print | | open with docReader Activity Details You have viewed this Ocue laruary 31 at 11:30… Eds Jan 31, 2018 11:20 m YARDI

Explanation / Answer

(5) Bar charts are common in the presentation of gender statistics. One of the axes, usually the x-axis, is formed by a qualitative variable with distinct categories.This variable can be sex or another breakdown variable such as urban/rural area, region, or wealth quintile. The other axis can represent absolute frequencies or percentages, sums or averages. Bar charts can be used to illustrate data that do not vary too greatly in magnitude.

Histogram can be used for number of brother and sister for the following reasons as histogram

(6)  

here x=4 appear one times, 5 appear two times,........and 10 appear 2 times. Cumulative frequency is calculated  sum of all previous frequencies up to the current point.

and relative frequency is calcualted as f/(toal frequncy=20)

x frequency cumulative frequency % relative frequency 4 1 1 5 5 2 3 10 6 3 6 15 7 4 10 20 8 4 14 20 9 4 18 20 10 2 20 10
