# I will investigate whether people picked at random can estimate line length better than angle size.

Extracts from this document...

Introduction

Estimating lines & Angles I will investigate whether people picked at random can estimate line length better than angle size. I will then develop it by studying my answers and see if e.g 11 year olds are at estimating line length or angle size than 16 year olds. Hypothesis: People are better at estimating line length than angle size 16 year olds are better at estimating line length than 11 year olds. Method: * I'll draw 3 Lines on plain paper at different angles so they can not use markings on the paper to guess or help them get the length. * I'll also draw 3 angles on plain paper at different angles so they can not use markings on the paper to guess or help them get the size. * Then I'll pick the students a random by first numbering all the students, then using the random number generator on the calculator I can find the students I want by converting that number - e.g 88 - to a person - e.g Joe Bloggs year 7 * Then we ...read more.

Conclusion

11 Hypothesis conclusion People are better at estimating line length than angle size - I proved this by showing that the mean error for line length estimates was considerably lower than angle size estimates. Line lengths Overall line error total was 3.12 compared to the Overall angle error total, which was 25.90. This clearly shows people had a higher error mean on angle estimates than line length. People are better at estimating line length than angle size Is a true statement 16 year olds are better at estimating line length than 11 year olds - I proved this in both line length and angle size by showing that year 11's, 16year olds have a lower error mean that year 7's, 11 years olds. 4.43 - is the year 7's overall mean line length compared to the year 11's overall mean length of 0.63 - which clearly states that 16year olds can estimate line length better that 11 year olds. 16 year olds are better at estimating line length than 11 year olds Is a true statement By Ashleigh Jones 1 30/04/2007 ...read more.

1. ## How well can you estimate the length of an object?

This is so that I can calculate the frequency density from the table and also I will draw a histogram from the results. I will then construct another 2 tables, this time to calculate the standard deviation for each year, as well as the mean.

2. ## This investigation looked to see whether the height on the shore would affect the ...

To investigate whether or not this is correct the ratio between the length of the shell and the aperture of the snails could be measured for snails in the upper and lower shores.

Wickelgren (1964) found that grouping the items in sets of three is most likely to improve recall however Bower and Winzenz (1969) said that reading numbers or words out loud before hand improves the recall. Rationale Bower's hierarchy consisted of words not frequently used in everyday language so therefore lacks ecological validity and can't be applied to everyday life.

2. ## Analysis of transcripts of speeches made by Tony Blair and George Bush to the ...

Blair uses strings of triplets such as, "murdered, tortured, brutalised" and "brutality, oppression, and fear". These build up an image of hostility against "Saddam's regime" and place emphasis on the cruelty and brutality of Saddam. He repeats the use of the word "regime" when describing the rule of Saddam.

1. ## Compare &amp;quot;Jones the Grocer&amp;quot; by Herbert Williams and &amp;quot;Not To Be Used For Babies&amp;quot; ...

The word "joy" shows us the complete opposite of hate. "Like the corner where is was always dusk And equatorial, aromatic with coffee beans, And calendars derisive of popularity, And the adverts twenty years out of date." In these lines the narrator shows how much he loves the shop.

2. ## An Investigation to see how the size of ashadow depends on the angle at ...

I expected that as the distance doubled, the length of the shadow would double but according to the ray diagrams, that was not the case. The length of the shadow increased by 1.6 times between changing the distance from 2 cm to 4 cm (ie:doubling the distance).

1. ## I have decided to test a group of pupils in order to investigate if ...

The five lines I will use will be: - * A straight line * One side of a triangle * A randomly shaped line * A circle * A zigzag line. I think that these lines will be sufficient enough to be tested.

2. ## Does people's ability to estimate lengths improve after being shown an accurate length?

My project is not centred around how people from different occupations, ages, or gender affect the results so a varied audience is much better. However in my ideal world, I would probably have about 80 results, 8 from each age group, and within each age group 4 from each gender.
