Apparently the mean score is 100, and the standard deviation is 15.

This means that 67% of the population will score between 85 and 115.

Higher scores are better.

The company selling the midyis system will give, as well as scores, predictions of what the child should be able to achieve at GCSE level. Schools can then use this to a) track a child's progress compared with their theoretical capability predicted by the test, and b) to see if they have "added value" by raising the child to achieve more (or less) than predicted.

What does a midyis score of 120 represent?

The Midyis score is standardized, so 100 is average. Somewhere around 116 would be one standard deviation about average, so that suggests 120 is just above the cusp to be "above average". However, that is just observed score and there is a huge margin of error in such assessments as trying to measuring attainment in the brain is complex. So in reality, what the child actually knows will be somewhere between 108-132 midyis score. From the midyis score alone, it does seem reasonable to ensure that student is prepared to go through university.

What is the formula in getting Mean Percentage score?

The formula for calculating the mean percentage score is to first add up all individual scores, then divide the total by the number of scores. This will give you the mean score. To convert the mean score to a percentage, you would then divide the mean score by the total possible score and multiply by 100. This will give you the mean percentage score.

What is a z-score?

z score is defined as z = (x-mean)/sd, where mean is the mean of the sample (or population) and sd is the standard deviation of the sample or the population. x is the raw score. z-score standardizes the data. The standardized data will have a zero mean and unit variance. It has numerous applications in statistics.

What does a MidYIS score of 154 represent?

Hi! An average MidYIS score is 100 so 154 is an extremely good standard. If your child keeps up the effort in achieving their obviously high potential they should be well on their way to A/A* s in GCSE and A-Level. It's highly likely that your child will be accepted into Oxford University if their obvious talent is nurtured and nourished throughout their school years. They are likely to be in the top 1% of the population so maybe MENSA would be an option?


What does it mean if the Z score of a test is equal to 0?

If the Z Score of a test is equal to zero then the raw score of the test is equal to the mean. Z Score = (Raw Score - Mean Score) / Standard Deviation


What does midyis skills measure?

MidYIS (Middle Years Information System) assesses a student's cognitive abilities, including verbal reasoning, non-verbal reasoning, and mathematical reasoning.

Is a negative z score always an indicator that the raw score is below the mean?

Yes.z = (raw score - mean)/standard error.Since the standard error is positive, z < 0 => (raw score - mean) < 0 => raw score < mean.


Is it true any score with value less than the population mean will have a negative z-score?

Yes. If a score is below the mean, the z score will be negative.


How do you find the mean from raw score z score and standard deviation?

To find the mean from a raw score, z-score, and standard deviation, you can use the formula: ( \text{Raw Score} = \text{Mean} + (z \times \text{Standard Deviation}) ). Rearranging this gives you the mean: ( \text{Mean} = \text{Raw Score} - (z \times \text{Standard Deviation}) ). Simply substitute the values of the raw score, z-score, and standard deviation into this formula to calculate the mean.


What does a negative z-score mean?

z-score of a value=(that value minus the mean)/(standard deviation). So if a value has a negative z-score, then it is below the mean.
