I counted pedestrians going up past me and down the street, in 2 different locations. In Broad Street, it was very busy so I might not have recorded everyone. Also, some people might have been counted twice because they turned around or came back past me again. In Fish Street, there weren’t many people, so I counted everyone easily.
The statement can be re-written using the words accuracy, accurate and sample count.
I counted pedestrians going past me up and down the street, in 2 different locations. In Broad Street, it was very busy so I might not have recorded everyone. This means my sample counting in Broad Street might not be accurate because I might not have counted all the people in my sample, so the result might have been less than it actually was. Also, some people might have been counted twice because they turned around or came back past me again. This means that I might have counted more people, and so my sample counting would be inaccurate. In Fish Street, there weren’t many people, so I counted everyone easily. Counting everyone easily means I am confident that this sample count was accurate as I didn’t miss anyone.
Cyfrais gerddwyr yn mynd heibio i mi ar y stryd, mewn 2 leoliad gwahanol. Roedd yn brysur iawn ar Broad Street, felly efallai nad oeddwn wedi cofnodi pawb. Hefyd, efallai bod rhai pobl wedi cael eu cyfri ddwywaith oherwydd eu bod wedi troi'n ôl neu wedi cerdded heibio i mi eto. Ar Fish Street, nid oedd llawer o bobl, felly cyfrais bawb yn hawdd.

Cyfrais gerddwyr yn mynd heibio i mi ar y stryd, mewn 2 leoliad gwahanol. Roedd yn brysur iawn ar Broad Street, felly efallai nad oeddwn wedi cofnodi pawb. Mae hyn yn golygu efallai na fydd fy nghyfrif sampl ar Broad Street yn fanwl gywir oherwydd efallai nad oeddwn wedi cyfrif yr holl bobl yn fy sampl, felly gallai'r cyfrif wedi bod yn llai nag yr oedd mewn gwirionedd. Hefyd, efallai bod rhai pobl wedi cael eu cyfri ddwywaith oherwydd eu bod wedi troi'n ôl neu wedi cerdded heibio i mi eto. Golyga hyn y gallaf fod wedi cyfrif mwy o bobl, ac felly ni fyddai fy nghyfrif sampl yn fanwl gywir. Ar Fish Street, nid oedd llawer o bobl, felly cyfrais bawb yn hawdd. Mae cyfrif pawb yn hawdd yn golygu fy mod yn hyderus fod y cyfrif sampl hwn yn fanwl gywir gan nad oeddwn yn methu unrhyw un.

I used data from the 2011 National Census to help me work out what jobs people have in Goole, Yorkshire. It may, however, be out of date now, although the National Census is well known and shares how it collects its data.

Defnyddiais ddata o Gyfrifiad Cenedlaethol 2011 i fy helpu i weithio allan pa swyddi sydd gan bobl yn Goole, Swydd Efrog. Fodd bynnag, gallan nhw fod yn hen erbyn hyn, er bod y Cyfrifiad Cenedlaethol yn hysbys ac yn rhannu sut mae'n casglu ei ddata.
I used secondary data from the 2011 National Census to help me work out what jobs people have in Goole, Yorkshire. It may, however, be out of date now, as it was published in 2011 so might be inaccurate, although the National Census is well known and shares how it collects its data, so it will have been recorded carefully and they will have counted everything, so will have been accurate in 2011.

We collected news articles about a music festival after it was cancelled. We highlighted positive and negative comments. Sometimes it was hard to decide if a comment was positive or negative and so we might have put more comments in the positive or negative category, this meant we might have been bias in how we categorised them. This means the results could be bias, so we haven’t actually measured the number of positive or negative comments accurately, which means our results might not be valid.
