Drawing Conclusions Essay

Computing Impact Information 3 -- Drawing Findings from Data

DRAWING A CONCLUSION FROM DATA

SUMMARY

This guide seeks to aid schools in drawing valid conclusions in the data collected. It looks at identifying trends, assessing reliability and validity of data and conclusions, and whether or not record analysis is necessary.

INTRODUCTION

After getting collected your details, you need to look at what it really teaches you. Sometimes (but very rarely) the conclusion is definitely obvious. In the event every single member of a examining club produced a huge gain in examining age and no member of the control group made such gain, then you could be fairly confident which the reading team benefited the pupils' reading ability! Inside the real world, however , data is rarely that clear lower. There will generally be variation between people and the amount of this may shed doubt on your conclusions. If an improvement is definitely shown, you have to judge if this improvement is significant.

Even if an important effect is noticed, you should consider the reliability of your conclusion - how specific can you be that what you do caused the result, rather than some other factors? Information takes you throughout the necessary steps to ensure that you get real value and meaning from your collected results. It works with quantitative data, as it is often difficult to draw general results from qualitative data.

IDENTIFYING TRENDS

You hope that attendance for study support in general, or at a specific activity, may have some considerable effect on the participants. Tendencies are important when you need to study the effect of different amounts of study support.

Examples could be:

В·

The effect of different degrees of attendance at study support on SEATED level accomplished at the end of the Key Level.

В·

The result of different range of attendances for a Maths club in Maths results at the end of your year.

В·

Progress of any measurable sports activities skills during the course of an extended system. What you are searching for is some kind of marriage between the things you provided and a measurable outcome. This is certainly called a correlation, and is greatest shown by simply plotting the effects on a graphdifferent types of correlation happen to be shown in Box 1 ) Strong great correlation

Elevating the amount of activity increases the considerable outcome noticeably. Weak confident correlation

Increasing the amount of activity increases the measurable outcome at some level. No relationship

The activity has no measurable impact on the outcome

Solid negative correlation

The activity substantially decreases the measured outcome (this can be desirable - e. g. If the activity was a ‘health club' as well as the outcome was fast food products eaten in a week). 1

Usually, the details on the chart will not along with an absolutely frequent pattern. The lines sketched on the charts in Field 1 just indicate basic trends inside the data. Various other patterns happen to be possible:

This sort of trend shows that the activity has an

first effect, but that after a little while the rate of

improvement becomes much less. This could be

useful in deciding the optimum length for the

activity.

This kind of pattern of trend shows that improvement

takes a when to ‘kick in'. This kind of also gives useful

details, this time for the minimum length

of the activity.
