 In Math we have tested our reaction time with our arms.We first tested out non dominant hand to see how fast it would react and it the reaction time was as quick.My dominant hand had a faster reaction time because It was my dominant hand and i'm used to using my right hand more than my left.  

Left Hand	Right Hand
120mm	60mm
160mm	260mm
210mm	60mm
120mm	90mm
80mm	70mm
total=690mm	total=540mm

Here are my results to prove that my dominant hand has a faster reaction than my non dominant hand.My non-dominant hand needs working on like I need to kind of use it more just to make my left hand react the same as my right hand.

Maths

 Mean:The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

E.g 10 + 10 +10 +10 + 10=50 50÷ 5=10.10

Who Invented Mean?

The Belgian statistician Quetelet (1796-1874), famous as the inventor of l'homme moyen, the average man, was one of the first scientists to use the mean as the representative value for an aspect of a population.

Who Invented Mode?An early use of the statistical concept of the mode was by English mathematician Karl Pearson (1857-1936) in 1895

Who invented Median?The idea of the median appeared in the 13th century in the Talmud, in order to fairly analyze divergent appraisals. However, the concept did not spread to the broader scientific community.

What is Mean?It is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the number of values on the list. To find the mean, add up all the values in the set. Then divide the sum by how many values there are.

What is Mode Math?The mode is the number that occurs most often in a data set.

What is Median Math?To find the Median, place the numbers in value order and find the middle number.

What did I learn in Maths this week?
-This week I was learning about packing circles.The way this is done is where you get a limited amount of circles and you have to have a suitable shape for the shapes.

E.g-you have 6 circles and you are wanting to have a shape that is stable shape to carry the 6 circles.
