INTRODUCTION In This project we have represented

data in different forms. Then we represented the given data in form of raw data , frequency table, tally marks , bar graph and frequency table. We have also calculated mean , mode and median. In this way we can arrange different kinds of data in a sustainable form.

TOPIC 1 SA – I MARKS

Raw data : 24, 19, 29, 22 ,30, 18, 22, 18 , 22,19, 18, 22, 18, 24, 25, 26, 28, 28, 16, 19, 18, 13, 21, 26, 25, 25 ,29, 26, 18 , 26, 26, 12, 24, 24, 27, 15, 28, 18. Range : Upper limit – Lower limit Range : 8 -1 = 7 Mean : sum of all observations / total observations Mean :783/35 = 22.3 Mode : highest occurring observation is 18. Median : median of this data is 24 .

TOPIC 2 ABSENTEES

Raw data : 1, 1, 0, 0, 0, 1, 1, 2, 2, 0, 3, 0, 1, 0, 2, 1. Range : Upper limit – lower limit Range : 3 – o = 3 Mean : sum of all observations/total observations Mean : 14/15 = 0.92 Mode : highest occurring observation is 0. Median : median of this data is 1.

Range : upper limit – lower limit Range : 12 – 1 = 11 Mode : highest occurring observation is football.

TOPIC 4 SURNAME LETTER

Raw data : 4, 8, 5, 5, 3, 4, 8, 8, 5, 5, 7, 6, 6, 5, 3, 5, 5, 8, 5, 6, 5, 6, 5, 8, 5, 5, 6, 5, 4, 4, 5, 5, 6, 5, 4. Range : upper limit – lower limit Range : 16 -1 = 15 Mean : sum of all observations/total observations Mean : 189/35 = 5.4 Mode : highest occurring observation is 5. Median : median of data is 5.

TOPIC 4 BIRTHDAY MONTHS

Raw data – Feb. April Feb. Oct August Dec March, August July Feb. Feb. Sep Feb. Oct April Oct Dec March Oct, Feb. Sep August, Feb. March, Sep, August Feb. March, Sep, March Oct August May Dec January, January.

Range : upper limit – lower limit Range : 8 – 0 = 8 Mode : highest occurring observation is February.

TOPIC 5 BLOOD GROUPS Raw data : B-, O-, B+, B+, O+, B+, B+, B-, B-, B+, B+, B+, O-, B+, O+, B+, B+, B+, O+, B+ ,B+, O+, B-, B-, O-, AB+, B+, B+, B+, B+, B+, O-, O+, B+. Range : upper limit – lower limit Range : 20 -1 = 19 Mode : highest occurring observation is B+.

TOPIC 6 TEMPERATURE Raw data : 33, 31, 31, 32, 31, 33, 32, 31, 31, 30, 29, 32, 32, 34, 32. Range : upper limit – lower limit Range : 7 – 3 = 4 Mode : highest occurring observation is 31 degree and 32 degree. Mean : sum of all observations/total observations Mean :474 / 15 = 31.6 Median : median of data is 31 degree.

TOPIC 7 PROBABILITY Raw data : 1, 1, 1, 0, 0, 2, 2, 3, 2, 2, 2, 1, 2, 2, 2, 2, 2 Range : upper limit – lower limit Range : 3 – 0 = 3 Mode : highest occurring observation is 2. Mean :sum of all observations/total observation Mean : 23/15 = 1.53 Median : median of data is 2.

MENSURATION Raw data Length of blackboard = 49 cm. Breadth of backboard = 96 cm. Length of window = 52 cm. Breadth of window = 142 cm. Length of classroom = 126 cm. Breadth of classroom = 249 cm.

CALCULATIONS Area : Blackboard = 4704 sq. cm. Window =7384 sq. cm. Classroom = 31374 sq. cm.

PERIMETER Blackboard = 290 cm. Window = 388 cm. Classroom = 750 cm.

CONCLUSION By making this project , we got to know about

the way of data handling. We learnt the method of finding mean, mode and median.

This project also taught us to work together as a group.

We also got a chance to make a power point presentation on this project which enhanced our computer skills.

So this project was very useful for us and we would like to make such kind of projects again and again.

THANK YOU.
