Investigation Into Students' Ability to Estimate

We have been given a task to work with the statistical side of maths.

We were told that a random sample of one hundred and fifty people were

asked to estimate the degree of an angle which looked like this:

[IMAGE]

Also each person was asked to estimate the length of a line which

looked something like this:

[IMAGE]

From this we were asked to think about what sort of conclusions we

could give for the analysed results. I thought about this and came up

with the following hypothesis:

"Males in the 11-18years age range will guess the angles and lengths

better than females in the 30+years age range."

I have chosen this hypothesis because it allows me to look at both age

and gender of the surveyed people.

(The actual measurement of the angle was 36.5degrees and the actual

measurement of the line was 4.35cm)

The data I have received from the survey is on the following pageâ€¦

PLAN:

To investigate this hypothesis I may need to use a number of methods

to calculate the data I will receive. I may need to use many

statistical tools which I already know; such as Averages, Standard

Deviation, Frequency Polygons, Histograms, Scatter Diagrams,

Cumulative frequency and maybe other methods which I will have to

research.

As the sample I am being given is random, it has a large range of

varied aged males and varied aged females. I need to divide the groups

up into the groups I have to work with according to my hypothesis.

Hare are the divided groups from the data:

Males aged 11-18years:

The factors that can be looked at are as follows: - · Set · Gender · Location of line / angle In order to test all these factors I will need a range of pupils selected at random from a range of sets. I have decided that

Nutrition assessments include clinical and dietary assessment, anthropometrics, as well as biochemical, laboratory immunologic and functional indices of nutritional status (Gibney, 2005). In epidemiological studies, different dietary investigation tools were designed to assess the

It is believed that if you hold knowledge and have an understanding of how people behave then you have the ability to manipulate this. Studies have shown that when a well-known task is carried out in the presence of others individuals perform to a higher standard than if the activity was performed alone. This is what is known as audience affects or social facilitation

Although some aspects of it still do not give 100% factual information, the information it does provide is an estimate. Those estimates still give investigators enough information about the skeletal remains that they can usually start moving forward in the investigation. A sub-category of anthropology is odontology. Usually these two disciplines work closely together when identifying human remains, especially if there are teeth involved

Many at-risk students are not performing on standardized tests when they are taught using traditional teaching methods of lectures, note taking, and assigned reading and questioning. Furthermore, at-risk students usually struggle, lose interest and motivation and often become embarrassed or depressed by failure when taught under these methods. Many at-risk students struggle with processing new information globally

It assesses how this failure was predictable in the long and short-term and what factors were involved. The two sources used for a deeper study are from America in Vietnam, by Guenter Lewy and The army and Vietnam by Andrew F. Krepinevich Jr. Their origins, purpose, values and limitations will be discussed to assess their usefullness for the investigation. The investigation

## Critical Thinking Theory

The value of critical thinking is lost if it is treated as a list of logical operations, and the possession of certain knowledge is regarded simply as a collection of information. The investigation of the relationship of a value judgment and the actual use may lead to a new assessment of the need for common concepts of critical thinking and the possession of certain knowledge in education (Paul,

## Student Assessment - Limitations of the IQ Test

882 Words | 4 PagesIQ test stands for an ‘intelligence quotient’ test, or a cognitive ability test and these tests are taken frequently by many people as a measure of one’s intelligence. The view that an IQ test accurately determines, or even estimate, and individual’s intelligence is very arguable, and has not been without controversy. IQ tests work on the notion of Symbolic Logic, and since this is not correlated with intelligence, there is uncertainty over what is being measured. The very notion of intelligence
