TITLE:
Continuous Variation
AIM:
To investigate continuous variation amongst students in your science class
MATERIALS:
•
•
•
•
Measuring tape/ruler
Pencil
Paper
Participants
PROCEDURES:
1. Measure the height of each member of your class.
2. From the list, make sure you have enough groups to take in all the measurements. (It
is possible that there may be a group with no individual results in it.)
3. Use the frequency table to draw a histogram showing how height varies among your
peers.

DISCUSSION:
Hereditary variety alludes to contrasts among the genomes of individuals from similar species. Hereditary variety inside an animal types can result from one or two

to smoke at those ages. The numbers would then dial down as the numbers increment (emotional fall would be seen
around 23 or thereabouts.) I in all actuality do accept that environmental variation can influence the trait inside this test, essentially on the grounds that as time
developed, technology did as well and common items. An individual's tallness in this investigation can be altered because of things like mishaps, ailments, and so on
As far as mishaps, an individual can encounter spinal breaks, which can then add to the lessening in their unique tallness. An irregularity, like scoliosis, can immensely
influence a singular's tallness. On the off chance that their spine is bended, it would be basically impossible (sensibly) to really precisely sort out the individual's
tallness, rather than them having a straight, typical spine.
SOURCE OF ERROR/ LIMITATION/ PRECAUTION:
2 wellsprings of error that can be recognized in this analysis was erroneously counting the people inside the different stature gatherings, and erroneously putting the

CONCLUSION:
In conclusion, the investigation of continuous variation conducted on the students within my class was a success, alongside the construction of the table and
histogram.

really must monitor these qualities, essentially in light of the fact that we are continually developing and changing, which brings about the development of our attributes
also. On the off chance that we monitor these attributes, we will actually want to precisely do things like purchase the right estimated shoe or right measured shirt.
