Question

This week we were introduced to the "normal curve," also known as the bell curve. Many human factors are normally distributed, and your task for this week's discussion is two describe two examples from your own life. I'll start with my own example, which is the amount of sleep I get per night. My average is about 7 hours, and the distribution of sleep time over many nights most likely has a normal distribution. Some nights I get less than 7 hours, some nights I get more. However, the frequency of data becomes less and less, the farther it is from 7. In other words, something like 10 hours of sleep is extremely uncommon, as is only getting 4 hours. On the other hand, 6.5 hours is relatively common, as is 7.5. If I graphed the amount of sleep I got over the last 100 nights, it would approximate the shape of a bell curve.

So, what are two examples from your own life?

Answer 1

(1) First example is from my classroom i collect the marks obtained by my classmates in a paper "statistics and probability " and i found that the average marks of my classmate is about 62 , so there are lot of students who got marks around 62 but there is less and less students as we move far from 62, i mean to say there are only few students who got marks above 90 and also there are only few students who got marks less than 40 , so if i graph marks obtained by my classmates i will get a normal curve

(2) Second example is related to food , on average i take about 3000 calories per day means most of the day my calorie intake is about 3000 calorie , but sometimes when there is a party i take around 6000 calorie but it happens only when there is a celebration which is once or twice in a month and sometimes when i got busy in something like gaming or stuffs , i forgot to eat a meal and that day i take around 1000 calorie only but it happens very less, so if we graph my calorie intake in a year we will get a normal curve
