Hi Everyone,

A few days ago my class did a data Analysis project. Our inquiry question was

Our inquiry Question

What is the length from your wrist to your finger tip?

 

1.Equipment

for this we only needed a Ruler

2.Procedure

was to ask for a classmates hand and measure then round to the nearest Centimeter

3. control standers

our control standers were Centimeters

4. My Predictions

before we did this project was that the average would be 16Cm

5. Our data organized

was in cm from least to greatest was

15, 15, 15, 16, 16, 16, 16, 16, 16, 16, 17, 17, 17, 17, 17, 17, 17, 17, 18, 18, 20

Mean:

30+15+32+32+32+16+34+34+34+34+18+18+20= 349 ÷ 21 = 16.6

Median:

The median is the middle # in the data stet 16.5cm

Mode:

The made is the number that occurs the most 17cm

Range:

20−15 = 5cm

There are no outliers

The Mean would be the most appropriate to use

I was slightly off with my predictions i thought the average would be 16cm but It was 17cm

I thought  that this was really fun to do and I would like to do another project like this again

Sincerely Kaiya
